Solution: Product of Array Except Self

Explore how to compute the product of all array elements except the current one using JavaScript. This lesson covers two approaches: a brute force method and an optimized bidirectional product accumulation. Understand their time and space complexity to improve problem-solving for coding interviews.

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
