# Top 3 Most Common Data Structures You Need to Know

Data structures are some of the foundational basics of programming

Knowledge of data structures is one of the foundational basics of programming. Having a better understanding and knowledge about algorithms and data structures is one of the most important topics to have and master as a developer.

I like to say that they are more like push-ups practices to our brains.

Some people tend to shy away from learning data structures and algorithms. I think we should embrace the goodness and niceties it comes with learning and understanding algorithms and data structure.

Having a better understating of them will enable us to solve problems a little more easily and understand concepts more quickly.

In this article, we are going to see the three most common Data structures you need to know.

• Stack
• Queue

A linked list is a linear data structure where each element is a separate object. It consists of a sequence of things that are linked in a linear order. They are also linked together using pointers so if you have to access one, you have to access the data sequentially.

Elements in a linked list are referred to as nodes and each node in a linked list is made up of a node and a pointer. Simply known as key for the values and next for the pointer.

The beginning of a linked list is known as the head and it points to the first element in the linked list, while the last element in the list is called a tail and points to the last element in the linked list.

The tail has not next and it’s always null as there is no other element in the list.

2. Stack

A stack is a linear data structure that follows a particular order in which the operations are performed. The order may be First In Last Out (FILO) OR Last In First Out (LIFO).

A little illustration about the stack is let’s say you are arranging some books on a shelf on top of each other, the last book on the stack is the first that you will always take out. So last in first out.

The stack consists mainly of two operations that are the push and pop. With a push, you are inserting something to the start of the stack while with pop you are removing and returning something at the top of the stack.

In a stack, you can peak that is returning what is at the start of the stack without deleting.

Application

• Expression evaluation
• Implement function calls and recursive programming.

3. Queue

A queue is a linear structure that follows a particular order in which the operations are performed. The order is First in First Out (FIFO).

Basic operations you can perform with a queue.

• N Queue — you are inserting an element to the end of the queue.
• D Queue — you are deleting an element from the beginning of the queue.

## Applications

These are the most common data structures that you need to know as a programmer. Thank you for following through this article to this far, I hope you found it helpful.

Living with a bad credit score for the years has been the bane of my existence and it has put me on so many limitations. I was always on the edge, trying to collect loans from these companies but it has been a hard knock life for me . My boyfriend was going through his own shit but somehow he told me about this hacker that his friend used to clear his bad credit score (ALIENMAN.HACKER AT GMAIL DOT COM). I was really doubtful because i have been scammed a couple of times but he convinced me that he has seen and heard reviews, it was really unbelievable. He decided to use this professional hacker himself when he had issues with the company he invested his bitcoins in and ALIENMAN.HACKER did a great job retrieving his bitcoins. Finally, I reached out to him with my fingers crossed. OMDS!!His customer service is top notch, I loved how swift his responses were and he helped me sort it out in less than a week. He increased my credit score up 734. I can't thank him enough. Contact ALIENMAN. HACKER for any hacking services you may need

## A Pure PHP Implementation Of The MessagePack Serialization Format

msgpack.php

A pure PHP implementation of the MessagePack serialization format.

## Installation

The recommended way to install the library is through Composer:

``````composer require rybakit/msgpack
``````

## Usage

### Packing

To pack values you can either use an instance of a `Packer`:

``````\$packer = new Packer();
\$packed = \$packer->pack(\$value);
``````

or call a static method on the `MessagePack` class:

``````\$packed = MessagePack::pack(\$value);
``````

In the examples above, the method `pack` automatically packs a value depending on its type. However, not all PHP types can be uniquely translated to MessagePack types. For example, the MessagePack format defines `map` and `array` types, which are represented by a single `array` type in PHP. By default, the packer will pack a PHP array as a MessagePack array if it has sequential numeric keys, starting from `0` and as a MessagePack map otherwise:

``````\$mpArr1 = \$packer->pack([1, 2]);               // MP array [1, 2]
\$mpArr2 = \$packer->pack([0 => 1, 1 => 2]);     // MP array [1, 2]
\$mpMap1 = \$packer->pack([0 => 1, 2 => 3]);     // MP map {0: 1, 2: 3}
\$mpMap2 = \$packer->pack([1 => 2, 2 => 3]);     // MP map {1: 2, 2: 3}
\$mpMap3 = \$packer->pack(['a' => 1, 'b' => 2]); // MP map {a: 1, b: 2}
``````

However, sometimes you need to pack a sequential array as a MessagePack map. To do this, use the `packMap` method:

``````\$mpMap = \$packer->packMap([1, 2]); // {0: 1, 1: 2}
``````

Here is a list of type-specific packing methods:

``````\$packer->packNil();           // MP nil
\$packer->packBool(true);      // MP bool
\$packer->packInt(42);         // MP int
\$packer->packFloat(M_PI);     // MP float (32 or 64)
\$packer->packFloat32(M_PI);   // MP float 32
\$packer->packFloat64(M_PI);   // MP float 64
\$packer->packStr('foo');      // MP str
\$packer->packBin("\x80");     // MP bin
\$packer->packArray([1, 2]);   // MP array
\$packer->packMap(['a' => 1]); // MP map
\$packer->packExt(1, "\xaa");  // MP ext
``````

Check the "Custom types" section below on how to pack custom types.

#### Packing options

The `Packer` object supports a number of bitmask-based options for fine-tuning the packing process (defaults are in bold):

The type detection mode (`DETECT_STR_BIN`/`DETECT_ARR_MAP`) adds some overhead which can be noticed when you pack large (16- and 32-bit) arrays or strings. However, if you know the value type in advance (for example, you only work with UTF-8 strings or/and associative arrays), you can eliminate this overhead by forcing the packer to use the appropriate type, which will save it from running the auto-detection routine. Another option is to explicitly specify the value type. The library provides 2 auxiliary classes for this, `Map` and `Bin`. Check the "Custom types" section below for details.

Examples:

``````// detect str/bin type and pack PHP 64-bit floats (doubles) to MP 32-bit floats
\$packer = new Packer(PackOptions::DETECT_STR_BIN | PackOptions::FORCE_FLOAT32);

// these will throw MessagePack\Exception\InvalidOptionException
\$packer = new Packer(PackOptions::FORCE_STR | PackOptions::FORCE_BIN);
\$packer = new Packer(PackOptions::FORCE_FLOAT32 | PackOptions::FORCE_FLOAT64);
``````

### Unpacking

To unpack data you can either use an instance of a `BufferUnpacker`:

``````\$unpacker = new BufferUnpacker();

\$unpacker->reset(\$packed);
\$value = \$unpacker->unpack();
``````

or call a static method on the `MessagePack` class:

``````\$value = MessagePack::unpack(\$packed);
``````

If the packed data is received in chunks (e.g. when reading from a stream), use the `tryUnpack` method, which attempts to unpack data and returns an array of unpacked messages (if any) instead of throwing an `InsufficientDataException`:

``````while (\$chunk = ...) {
\$unpacker->append(\$chunk);
if (\$messages = \$unpacker->tryUnpack()) {
return \$messages;
}
}
``````

If you want to unpack from a specific position in a buffer, use `seek`:

``````\$unpacker->seek(42); // set position equal to 42 bytes
\$unpacker->seek(-8); // set position to 8 bytes before the end of the buffer
``````

To skip bytes from the current position, use `skip`:

``````\$unpacker->skip(10); // set position to 10 bytes ahead of the current position
``````

To get the number of remaining (unread) bytes in the buffer:

``````\$unreadBytesCount = \$unpacker->getRemainingCount();
``````

To check whether the buffer has unread data:

``````\$hasUnreadBytes = \$unpacker->hasRemaining();
``````

If needed, you can remove already read data from the buffer by calling:

``````\$releasedBytesCount = \$unpacker->release();
``````

With the `read` method you can read raw (packed) data:

``````\$packedData = \$unpacker->read(2); // read 2 bytes
``````

Besides the above methods `BufferUnpacker` provides type-specific unpacking methods, namely:

``````\$unpacker->unpackNil();   // PHP null
\$unpacker->unpackBool();  // PHP bool
\$unpacker->unpackInt();   // PHP int
\$unpacker->unpackFloat(); // PHP float
\$unpacker->unpackStr();   // PHP UTF-8 string
\$unpacker->unpackBin();   // PHP binary string
\$unpacker->unpackArray(); // PHP sequential array
\$unpacker->unpackMap();   // PHP associative array
\$unpacker->unpackExt();   // PHP MessagePack\Type\Ext object
``````

#### Unpacking options

The `BufferUnpacker` object supports a number of bitmask-based options for fine-tuning the unpacking process (defaults are in bold):

1. The binary MessagePack format has unsigned 64-bit as its largest integer data type, but PHP does not support such integers, which means that an overflow can occur during unpacking.

2. Make sure the GMP extension is enabled.

3. Make sure the Decimal extension is enabled.

Examples:

``````\$packedUint64 = "\xcf"."\xff\xff\xff\xff"."\xff\xff\xff\xff";

\$unpacker = new BufferUnpacker(\$packedUint64);
var_dump(\$unpacker->unpack()); // string(20) "18446744073709551615"

\$unpacker = new BufferUnpacker(\$packedUint64, UnpackOptions::BIGINT_AS_GMP);
var_dump(\$unpacker->unpack()); // object(GMP) {...}

\$unpacker = new BufferUnpacker(\$packedUint64, UnpackOptions::BIGINT_AS_DEC);
var_dump(\$unpacker->unpack()); // object(Decimal\Decimal) {...}
``````

### Custom types

In addition to the basic types, the library provides functionality to serialize and deserialize arbitrary types. This can be done in several ways, depending on your use case. Let's take a look at them.

#### Type objects

If you need to serialize an instance of one of your classes into one of the basic MessagePack types, the best way to do this is to implement the CanBePacked interface in the class. A good example of such a class is the `Map` type class that comes with the library. This type is useful when you want to explicitly specify that a given PHP array should be packed as a MessagePack map without triggering an automatic type detection routine:

``````\$packer = new Packer();

\$packedMap = \$packer->pack(new Map([1, 2, 3]));
\$packedArray = \$packer->pack([1, 2, 3]);
``````

More type examples can be found in the src/Type directory.

#### Type transformers

As with type objects, type transformers are only responsible for serializing values. They should be used when you need to serialize a value that does not implement the CanBePacked interface. Examples of such values could be instances of built-in or third-party classes that you don't own, or non-objects such as resources.

A transformer class must implement the CanPack interface. To use a transformer, it must first be registered in the packer. Here is an example of how to serialize PHP streams into the MessagePack `bin` format type using one of the supplied transformers, `StreamTransformer`:

``````\$packer = new Packer(null, [new StreamTransformer()]);

\$packedBin = \$packer->pack(fopen('/path/to/file', 'r+'));
``````

More type transformer examples can be found in the src/TypeTransformer directory.

#### Extensions

In contrast to the cases described above, extensions are intended to handle extension types and are responsible for both serialization and deserialization of values (types).

An extension class must implement the Extension interface. To use an extension, it must first be registered in the packer and the unpacker.

The MessagePack specification divides extension types into two groups: predefined and application-specific. Currently, there is only one predefined type in the specification, Timestamp.

Timestamp

The Timestamp extension type is a predefined type. Support for this type in the library is done through the `TimestampExtension` class. This class is responsible for handling `Timestamp` objects, which represent the number of seconds and optional adjustment in nanoseconds:

``````\$timestampExtension = new TimestampExtension();

\$packer = new Packer();
\$packer = \$packer->extendWith(\$timestampExtension);

\$unpacker = new BufferUnpacker();
\$unpacker = \$unpacker->extendWith(\$timestampExtension);

\$packedTimestamp = \$packer->pack(Timestamp::now());
\$timestamp = \$unpacker->reset(\$packedTimestamp)->unpack();

\$seconds = \$timestamp->getSeconds();
\$nanoseconds = \$timestamp->getNanoseconds();
``````

When using the `MessagePack` class, the Timestamp extension is already registered:

``````\$packedTimestamp = MessagePack::pack(Timestamp::now());
\$timestamp = MessagePack::unpack(\$packedTimestamp);
``````

Application-specific extensions

In addition, the format can be extended with your own types. For example, to make the built-in PHP `DateTime` objects first-class citizens in your code, you can create a corresponding extension, as shown in the example. Please note, that custom extensions have to be registered with a unique extension ID (an integer from `0` to `127`).

More extension examples can be found in the examples/MessagePack directory.

## Exceptions

If an error occurs during packing/unpacking, a `PackingFailedException` or an `UnpackingFailedException` will be thrown, respectively. In addition, an `InsufficientDataException` can be thrown during unpacking.

An `InvalidOptionException` will be thrown in case an invalid option (or a combination of mutually exclusive options) is used.

## Tests

Run tests as follows:

``````vendor/bin/phpunit
``````

Also, if you already have Docker installed, you can run the tests in a docker container. First, create a container:

``````./dockerfile.sh | docker build -t msgpack -
``````

The command above will create a container named `msgpack` with PHP 8.1 runtime. You may change the default runtime by defining the `PHP_IMAGE` environment variable:

``````PHP_IMAGE='php:8.0-cli' ./dockerfile.sh | docker build -t msgpack -
``````

See a list of various images here.

Then run the unit tests:

``````docker run --rm -v \$PWD:/msgpack -w /msgpack msgpack
``````

#### Fuzzing

To ensure that the unpacking works correctly with malformed/semi-malformed data, you can use a testing technique called Fuzzing. The library ships with a help file (target) for PHP-Fuzzer and can be used as follows:

``````php-fuzzer fuzz tests/fuzz_buffer_unpacker.php
``````

#### Performance

To check performance, run:

``````php -n -dzend_extension=opcache.so \
-dpcre.jit=1 -dopcache.enable=1 -dopcache.enable_cli=1 \
tests/bench.php
``````

You may change default benchmark settings by defining the following environment variables:

For example:

``````export MP_BENCH_TARGETS=pure_p
export MP_BENCH_ITERATIONS=1000000
export MP_BENCH_ROUNDS=5
# a comma separated list of test names
export MP_BENCH_TESTS='complex array, complex map'
# or a group name
# export MP_BENCH_TESTS='-@slow' // @pecl_comp
# or a regexp
# export MP_BENCH_TESTS='/complex (array|map)/'
``````

Another example, benchmarking both the library and the PECL extension:

``````MP_BENCH_TARGETS=pure_p,pure_u,pecl_p,pecl_u \
php -n -dextension=msgpack.so -dzend_extension=opcache.so \
-dpcre.jit=1 -dopcache.enable=1 -dopcache.enable_cli=1 \
tests/bench.php
``````

Example output

``````Filter: MessagePack\Tests\Perf\Filter\ListFilter
Rounds: 3
Iterations: 100000

If you accumulate data on which you base your decision-making as an organization, you should probably think about your data architecture and possible best practices.

If you accumulate data on which you base your decision-making as an organization, you most probably need to think about your data architecture and consider possible best practices. Gaining a competitive edge, remaining customer-centric to the greatest extent possible, and streamlining processes to get on-the-button outcomes can all be traced back to an organization’s capacity to build a future-ready data architecture.

In what follows, we offer a short overview of the overarching capabilities of data architecture. These include user-centricity, elasticity, robustness, and the capacity to ensure the seamless flow of data at all times. Added to these are automation enablement, plus security and data governance considerations. These points from our checklist for what we perceive to be an anticipatory analytics ecosystem.

## Создание пагинации с помощью jQuery

В этой статье мы увидим, как создать пагинацию с помощью jquery. Мы создадим разбиение на страницы jquery, используя несколько способов. Вы можете создать разбиение на страницы, используя разные способы, такие как создание разбиения на страницы с помощью простого HTML, вы можете создать разбиение на страницы в laravel, используя метод paginate(). Кроме того, создайте разбиение на страницы laravel livewire, разбиение на страницы с помощью бутстрапа.

Мы создадим простую пагинацию jquery. Кроме того, создайте разбиение на страницы с помощью jquery без плагина и создайте разбивку на страницы jquery с помощью кнопок «Далее» и «Предыдущий».

Итак, давайте посмотрим динамическую нумерацию страниц в jquery и бутстраповскую нумерацию страниц в jquery.

Пример:

В этом примере мы создадим пагинацию с помощью jquery без использования плагина. Кроме того, вы можете настроить пагинацию.
