Solution: Product of Array Except Self

Explore how to solve the product of array except self problem efficiently. Learn to implement a linear time algorithm in Java that avoids division by accumulating left and right products. Understand both brute force and optimized methods along with their time and space complexities to prepare 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
