Solution: Product of Array Except Self

Explore how to calculate the product of all elements in an integer array except the current one, without using division and maintaining O(n) time complexity. Understand brute force and optimized bidirectional product accumulation techniques, analyzing their time and space complexities to effectively solve this common coding challenge.

Statement

You’re given an integer array, nums. Return a resultant array product so that product[i] is equal to the product of all the elements of nums except nums[i].

Write an algorithm that runs in O(n)O(n) time without using the division operation.

Constraints:

  • 22 \leq nums.length 103\leq 10^3
