Mapping Arrays-To-Structs And Structs-To-Arrays

When mapping one data-set onto another data-set in ColdFusion, we can usually use the built-in .map() functions. This works great when the input and the output data-sets are the same type. But, every now and then, I want to map an Array onto a Struct; or, a Struct onto an Array; which isn’t something that the current mapping functions cater to. Normally, I implement this type of mapping with a for-loop; but, as a sort of code-kata, I wanted to see what a more “functional” type of solution might look like in Lucee CFML 5.3.6.61.

With the built-in mapping functions, the resultant data-set is defined by the return value of the iterator / operator function. But, when the mapping operation changes the underlying data-type, using the return value as the drive feels a bit awkward. For example, how would you map an Array item onto a Struct entry using a return value? One option would be to return the value as some sort of tuple:

Here, the return value is a “two tuple” in which the first item represents the “Key” in the resultant Struct; and, the second item represents the “Value” in the resultant Struct. This “works”; but, is quite unattractive and is hard to understand if you didn’t write the code.

Another option would be to ignore the return value altogether and use a passed-in “mapper” function:

Here, the mapTo() function, which is passed to the each iteration of the operator, takes two arguments - key and value - which drive the resultant Struct collection. To me, this feels more clear; and, even allows us to skip items within the array (should we want to do that).

How to Print an Array in Java

Introduction

Printing an array is a quick way to give us visibility on the values of the contents inside. Sometimes the array values are the desired output of the program.

In this article, we’ll take a look at how to print an array in Java using four different ways.

While the “best way” depends on what your program needs to do, we begin with the simplest method for printing and then show more verbose ways to do it.

#java #array #how to print an array in java #array in java #print an array in java #print

Difference between Array and Map

An array is a collection of items stored at contiguous memory locations. The idea is to store multiple items of the same type together. This makes it easier to calculate the position of each element by simply adding an offset to a base value, i.e., the memory location of the first element of the array (generally denoted by the name of the array).

The diagrammatic representation of the Array is given below:

Program 1:

Below is an illustration of a 1D array:

  • C++

// C++ program to illustrate 1D array

#include <bits/stdc++.h>

**using** **namespace** std;

// Driver Code

**int** main()

{

// Given array

**int** arr[] = { 6, 10, 5, 0 };

// Print the array elements

**for** (``**int** i = 0; i < 4; i++) {

cout << arr[i] << " "``;

}

**return** 0;

}

Output:

6 10 5 0

Program 2:

Below is an illustration of a 2D array:

// C++ program to illustrate 1D array

#include <bits/stdc++.h>

**using** **namespace** std;

// Driver Code

**int** main()

{

// A 2D array with 3 rows and

// 2 columns

**int** x[3][2] = { { 0, 1 }, { 2, 3 }, { 4, 5 } };

// Print each array element value

// Traverse row

**for** (``**int** i = 0; i < 3; i++) {

// Traverse column

**for** (``**int** j = 0; j < 2; j++) {

// Print element

cout << "Element at x[" << i

<< "][" << j

<< "]: "``;

cout << x[i][j] << endl;

}

}

**return** 0;

}

Output:

Element at x[0][0]: 0
Element at x[0][1]: 1
Element at x[1][0]: 2
Element at x[1][1]: 3
Element at x[2][0]: 4
Element at x[2][1]: 5

Map:

map is an associative container that stores elements in a mapped fashion. Each element has a key value and a mapped value. No two mapped values can have equal key values.

The diagrammatic representation of Map is given below:

Program 1:

Below is an illustration of a map:

// C++ program to illustrate Map

#include <bits/stdc++.h>

**using** **namespace** std;

// Driver Code

**int** main()

{

// Empty map container

map<``**int**``, **int**``> gquiz1;

// Insert elements in Map

gquiz1.insert(pair<``**int**``, **int**``>(1, 40));

gquiz1.insert(pair<``**int**``, **int**``>(2, 30));

gquiz1.insert(pair<``**int**``, **int**``>(3, 60));

// Iterator to iterate Map

map<``**int**``, **int**``>::iterator itr;

cout << "\nThe map gquiz1 is : \n"``;

cout << "\tKEY\tELEMENT\n"``;

// Print map gquiz1

**for** (itr = gquiz1.begin();

itr != gquiz1.end(); ++itr) {

cout << '\t' << itr->first

<< '\t' << itr->second

<< '\n'``;

}

**return** 0;

}

Output:

The map gquiz1 is : 
    KEY    ELEMENT
    1    40
    2    30
    3    60

Program 2:

Below is an illustration of an unordered map:

// C++ program to illustrate Map

#include <bits/stdc++.h>

**using** **namespace** std;

// Driver Code

**int** main()

{

// Declaring umap of <string, int>

// type key will be of string and

// mapped value will be of doubl

unordered_map<string, **int**``> umap;

// Insert values by using [] operator

umap[``"GeeksforGeeks"``] = 10;

umap[``"Practice"``] = 20;

umap[``"Contribute"``] = 30;

// Traversing an unordered map

// and print the key-value pairs

**for** (``**auto** x : umap)

cout << x.first << " "

<< x.second << endl;

**return** 0;

}

Output:

Contribute 30
GeeksforGeeks 10
Practice 20

Program 3:

Below is an illustration of a multimap:

// C++ program to illustrate Multimap

#include <bits/stdc++.h>

**using** **namespace** std;

// Driver Code

**int** main()

{

// Empty multimap container

multimap<``**int**``, **int**``> gquiz1;

// Insert elements

gquiz1.insert(pair<``**int**``, **int**``>(1, 40));

gquiz1.insert(pair<``**int**``, **int**``>(2, 30));

// Iterator

multimap<``**int**``, **int**``>::iterator itr;

cout << "\nThe multimap gquiz1 is : \n"``;

cout << "\tKEY\tELEMENT\n"``;

// Print multimap gquiz1

**for** (itr = gquiz1.begin();

itr != gquiz1.end(); ++itr) {

cout << '\t' << itr->first

<< '\t' << itr->second

<< '\n'``;

}

**return** 0;

}

Output:

The multimap gquiz1 is : 
    KEY    ELEMENT
    1    40
    2    30

Program 4:

Below is an illustration of an unordered multimap:

// C++ program to illustrate

// unordered multimap

#include <bits/stdc++.h>

**using** **namespace** std;

// Driver Code

**int** main()

{

// Empty initialization

unordered_multimap<string, **int**``> umm1;

// Initialization by intializer list

unordered_multimap<string, **int**``> umm2(

{ { "apple"``, 1 },

{ "ball"``, 2 },

{ "apple"``, 10 },

{ "cat"``, 7 },

{ "dog"``, 9 },

{ "cat"``, 6 },

{ "apple"``, 1 } });

// Traversing an unordered_multimap

// and print the elements stored

**for** (``**auto** x : umm2) {

cout << x.first << " "

<< x.second << endl;

}

**return** 0;

}

Output:

dog 9
cat 6
cat 7
ball 2
apple 1
apple 10
apple 1

What is Maps.me (MAPS) | What is Maps.me token | What is MAPS token

Maps.me 2.0 aims to be the ultimate travel companion and your passport to the new financial system. Powered by Serum and running on the fast and scalable Solana blockchain, Maps.me and its 140mm users represent a one-in-a-kind opportunity to accelerate the worldwide adoption of DeFi. MAPS tokens will bind Maps.me’s users and provide familiar travel reward programs and discounts, as well as governance features on certain aspects of ecosystem.

About MAPS

Maps.me 2.0 has both online and offline maps while offering DeFi functionalities to its 100M+ users.

Powering Maps.me 2.0 is the MAPS token which may provide token holders with 100% of the platform’s net revenues.

Token-holders using the app will also benefit from personalized promotions and rewards, likely driving adoption, retention, and virality of MAPS within the community. There are very few apps with a user base as large as ours, so Maps.me is positioned to quickly put DeFi financial services in the hands of many.

Furthermore, users utilize our app throughout their entire journey/travel process: we can therefore develop a travel- and wallet-oriented ecosystem to instill new user habits with regards to,

  • Payments
  • Accommodation booking
  • Fund transfers
  • Asset management

Our offered financial services are decentralized, which contrasts with the centralized nature of Robinhood (brokerage), Paypal (payments), and Revolut (fintech banking).

Maps.me is a popular mapping application that works similar to Google Maps except users can access it offline. But why is it relevant to crypto? Maps 2.0 introduces new financial products and services on the platform, allowing users to store assets, convert currencies, transfer funds, and make payments digitally.

Decentralized finance (DeFi) has enabled a new wave of innovations on the blockchain. It has helped expand the use cases for digital assets since it allows integration with any platform. And Maps is one of the biggest applications today that have transitioned to adopt DeFi technology.

Maps is a travel and navigation application that allows users to access maps both online and offline. Lately, Maps has introduced new digital finance features built on the  Solana blockchain. With a remarkable user base actively using the platform, it can become a springboard for greater DeFi adoption.

Background

Maps.me is an application owned by the Mail.ru group, a leading internet business firm based in Russia, which is also backed by other prominent firms like Alibaba, Naspers, and Tencent. With the aim of maximizing the application and tapping on its growing user base, the team behind the project worked on introducing DeFi features on the platform.

Maps has also been working closely with Alameda Research and FTX Exchange’s Sam Bankman-Fried, who also happens to be one of the advisors for  Oxygen protocol, a Solana-based exchange. In order to help bring liquidity to Oxygen, Maps is hoping to make them work together to be able to tap Map’s rich user base.

What is Maps.me?

Maps.me is a mapping application that users can access offline. It functions almost similarly with Google Maps, only that Maps.me can work without internet access. Across the world, the platform has recorded over 140 million users utilizing it for their travel needs, as well as an aid for directions.

Maps 2.0 introduces new financial products and services on the platform. Through this upgrade, users can finally store assets, perform currency exchange, transfer money, and make payments digitally. One of its biggest additions includes the integration of DeFi on Maps 2.0.

Maps’s digital wallet can facilitate peer-to-peer transactions. This means that it does not need any intermediary to conduct the exchange between users worldwide, making it a more affordable and censorship-resistant platform for remittances and cross-border payments.

Maps 2.0

If you are a business owner, you also will not need to list your property on third-party websites or applications, which can be expensive for the owners, as well as the consumers. With Maps as the all-in-one platform, users can finally make direct bookings and payments without leaving the application. In addition, businesses can benefit from doing away with intermediaries and the extra costs that come with them.

Besides the DeFi services that will be made available to the updated Maps platform, the project will also be partnering with local businesses to promote both their needs as well as their users. This ecosystem is expected to create a richer use case with personalized promotions, loyalty programs, branded content integrated within the map, and the opportunity to claim a business and increase its visibility with utmost convenience.

The economic model of Maps 2.0 will be built on top of the Solana blockchain and powered by the Serum protocol. This enables network attributes like faster transaction settlement times, low transaction fees, network security, and composability. Furthermore, the platform will also introduce a native token called MAPS, which would enable the platform to reward its users and holders for their app usage. In addition, the holders of the token will be given 100% of the net revenue that the platform makes.

Along with the token, Maps 2.0 will integrate a digital wallet, which can be used to store the users’ cryptocurrencies or other supported assets, conduct money transfers worldwide, and trade between the platform’s supported assets.

Developers of the platform will benefit from Maps 2.0’s deployment on the Solana blockchain as one of its biggest attributes is ‘composability.’ Anyone can build on the applications that are already on the platform. Devs can also make improvements from Maps 2.0, as well as create new protocols that complement those that already exist.

MAPS Token

As already mentioned, MAPS token enables a reward system designed to benefit its holders and app users. They can earn from privacy-preserving, personalized promotions too, helping the application cultivate its user base long-term. This token can also be used as a medium of exchange on the platform.

To ensure the sustainability of the platform’s growth, it follows a deflationary token model. There are only 10,000,000,000 MAPS tokens in existence, and no more will be minted in the future. Its total supply will also continuously decrease over time as the tokens that are bought back are burned.

Anyone can purchase MAPS tokens, except those who live in the United States, China, or other countries where it is prohibited.

How Does the Platform Generate Revenue?

MAPS holders will be able to earn their share of the revenue from services provided by the platform. These include revenue out of trading fees, fees from credit card transactions, fees from currency conversions, advertising fees, referral commissions, and many other products.

Other Benefits to Holding MAPS?

First off, frequent users of the application and those who promote listed locations on the platform earn MAPS tokens as a reward. Holders also enjoy lower fees and higher rewards from products and services available on the platform.

Another benefit of holding the native token is the opportunity to take part in the governance mechanism for the platform. This voting function allows users to take control of the application, especially on matters concerning upgrades, amendments to the reward structure and adding or modifying products and services, among others.

Business owners who also hold MAPS earn benefits from it as well. For one, holding the token will help them achieve better visibility as their locations are highlighted to users of the platform. This also means that they can be categorized into ‘premium listings,’ which gives them a good position in user searches.

Sam Bankman-Fried and Maps 2.0

With Maps’s collaboration with Sam Bankman-Fried, the pioneer of the Serum Project, FTX Exchange and the founder of Alameda Research, as one of their consultants, users can expect a platform developed to fit what anyone would need in a DeFi platform.

Maps has also been reportedly working on linking the application to the Oxygen protocol for their brokerage and exchange needs. As one of the newly developed exchanges in the DeFi space, Oxygen can substantially benefit from this partnership as they will be able to access a body of users that Maps has amassed.
