Given an array of integers, and a value, return the second index of the occurrence of that value in the array. If the value does not appear in the array, or if the value appears only once, return -1.


secondIndexOf([3, 7, 2], 2) → -1
secondIndexOf([5, 7, 5], 5) → 2
secondIndexOf([8, 8, 5, 1, 4], 8) → 1
