Given an integer array
nums, return an array
answer such that
answer[i] is equal to the product of all the elements of
The product of any prefix or suffix of
nums is guaranteed to fit in a 32-bit integer.
You must write an algorithm that runs in
O(n) time and without using the division operation.
Input: nums = [1,2,3,4] Output: [24,12,8,6]
Input: nums = [-1,1,0,-3,3] Output: [0,0,9,0,0]
2 <= nums.length <= 105
-30 <= nums[i] <= 30
numsis guaranteed to fit in a 32-bit integer.
Follow up: Can you solve the problem in
O(1) extra space complexity? (The output array does not count as extra space for space complexity analysis.)
