Given an array of numbers, create a function which returns the same array but with each element's index in the array added to itself. This means you add 0 to the number at index 0, add 1 to the number at index 1, etc...
addIndexes([0, 0, 0, 0, 0]) ➞ [0, 1, 2, 3, 4]
addIndexes([1, 2, 3, 4, 5]) ➞ [1, 3, 5, 7, 9]
addIndexes([5, 4, 3, 2, 1]) ➞ [5, 5, 5, 5, 5]
You'll only get numbers in the array.
