sumArrays


Given two arrays of equal length, return a new array where each element is the sum of the corresponding two elements in the original arrays.


sumArrays([1, 1], [4, 10]) → [5, 11]
sumArrays([2, 4, 6], [6, 4, 2]) → [8, 8, 8]
sumArrays([0, 0, 0, 0], [1, 2, 3, 4]) → [1, 2, 3, 4]

...Save, Compile, Run (ctrl-enter)

int[] sumArrays(int[] a, int[] b) { }
