Write a method, that will get an integer array as parameter and will process every number from this array.
Return a new array with processing every number of the input-array like this:
If the number has an integer square root, take this, otherwise square the number.
Example
[4,3,9,7,2,1] -> [2,9,3,49,4,1]
Notes
The input array will always contain only positive numbers, and will never be empty or null.
