# Squares of a Sorted Array

Posted: 10 Mar, 2021
Difficulty: Easy

## PROBLEM STATEMENT

#### For example :

``````Input:
‘ARR’ = [-6,-3, 2, 1, 5]

If we take a square of each element then the array/list will become [36, 9, 4, 1, 25].
Then the sorted array/list will be [1, 4, 9, 25, 36].

Output :
[1, 4, 9, 25, 36].
``````

#### Input Format:

``````The first line of input contains a single integer ‘T’, representing the number of test cases.
Then the ‘T’ test cases follow.

The first line of each test case contains a single integer ‘N’ denoting the size of ‘ARR’.

The second line contains ‘N’ space-separated distinct integers denoting the array elements.
``````

#### Output format:

``````For each test case, print the array elements separated by a single space.

The output of every test case will be printed in a separate line.
``````

#### Note :

``````You don’t have to print anything, it has already been taken care of. Just implement the given function.
``````

#### Constraints

``````1 <= T <=100
1 <= N <= 10^4
-10^4 <=  ‘ARR[i]’ <= 10^4

Where 'ARR[i]' denotes the value of 'ARR' at index 'i'.

Time limit: 1 sec
