In the fourth episode of Idiomatic Kotlin's Advent of Code series, we will be tackling input sanitization and validation challenges.
Input sanitization and validation feels like a problem as old as programming itself. User input can’t always be trusted, and ensuring it takes the exact form that we, as programmers expect, can take serious brain power.
In today’s episode, we will tackle a challenge that’s all about this topic – Day 4 of Advent of Code 2020! Stick around for the challenge and an elegant solution, implemented of course in Kotlin!

When working with location services, it is important that the information you collect is accurate for your users or clients. This will prevent any mistakes in shipping, billing, and many other aspects of operations that rely on correct location information. For businesses that have applications using location services, this is especially important as any incorrect data can mean the displacement of goods or interrupted services.
The following APIs will allow you to fully validate street addresses by first parsing address data input and then verifying and normalizing the information. The last two APIs will also allow you to geocode and reverse geocode an address to receive more accurate location data for your applications.

In this tutorial, let’s discuss what data validation is and how it can be implemented in MS-Excel. Let’s start!!!
Data Validation is one of the features in MS-Excel which helps in maintaining the consistency of the data in the spreadsheet. It controls the type of data that can enter in the data validated cells.
Now, let’s have a look at how data validation works and how to implement it in the worksheet:
To apply data validation for the cells, then follow the steps.
1: Choose to which all cells the validation of data should work.
2: Click on the DATA tab.
3: Go to the Data Validation option.
4: Choose the drop down option in it and click on the Data Validation.
Once you click on the data validation menu from the ribbon, a box appears with the list of data validation criteria, Input message and error message.
Let’s first understand, what is an input message and error message?
Once, the user clicks the cell, the input message appears in a small box near the cell.
If the user violates the condition of that particular cell, then the error message pops up in a box in the spreadsheet.
The advantage of both the messages is that the input and as well as the error message guide the user about how to fill the cells. Both the messages are customizable also.
Let us have a look at how to set it up and how it works with a sample
