Given an array
nums of n integers where n > 1, return an array
output such that
output[i] is equal to the product of all the elements of
Constraint: It's guaranteed that the product of the elements of any prefix or suffix of the array (including the whole array) fits in a 32 bit integer.
Note: Please solve it without division and in O(n).
Could you solve it with constant space complexity? (The output array does not count as extra space for the purpose of space complexity analysis.)
