Solution: Product of Array Except Self

Explore two methods to solve the product of array except self problem efficiently. Understand brute force and optimized bidirectional product accumulation approaches to prepare for coding interviews in Go.

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
