Learn the syntax, data types, and operations essential for programming in Scala

Become a Scala Developer

In this module, we will learn Scala from the ground up. This module aims to teach us how to write basic programs, assuming we have no prior knowledge of the language. We will start with a brief introduction to Scala to understand its functionality and applications. We will then move discuss the key features and functions of the language (data types, functions, classes, etc.) in detail. In the end, we will have all the basic knowledge of how to program in Scala.

Learn Scala from Scratch

## Problem Statement

You are given an Array of integers. The Array needs to be modified in such a way that it should contain the squares of the original values at the same index as the original values. 

For instance, if the element at index **0** is **5**, after modification it should be **25**.

### Input

The input will be the array `testArray` which stores the array to be modified.

> `testArray` has already been declared for you. 


### Output
The output will be the modified `testArray`. 

### Sample Input
```
(1,2,3)
```

### Sample Output
```
(1,4,9)
```
### Test Yourself

Write your code in the given area. Try the exercise by yourself first, but if you get stuck, the solution has been provided. Good luck!
