Problem: Product of Array Except Self

Understand how to solve the product of array except self problem using a two-pass algorithm that calculates prefix and suffix products. Learn to implement this efficient O(n) time and O(1) extra space solution in Go, enhancing your skills in array manipulation and algorithm optimization.

Statement

Given an integer array nums, return an array answer where answer[i] represents the product of all elements in nums except nums[i].

You must design an algorithm that operates in O(n)O(n) time complexity and does not use the division operation.

Note: The product of any prefix or suffix of nums is guaranteed to fit in a 3232-bit integer.

Constraints:

  • 22 \leq ...
