Problem: Product of Array Except Self

Understand how to solve the product of array except self problem using arrays in C#. Explore an efficient two-pass approach that calculates prefix and suffix products without division, achieving O(n) time complexity and constant extra space. Learn to implement this solution step-by-step to improve array handling and algorithm design skills.

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 ...
