Solution: Backspace String Compare

Understand how to solve the backspace string compare problem by using two pointers moving from right to left, tracking skip counts for backspaces. Learn to implement an efficient solution that compares characters on the fly without extra space. This lesson teaches you to achieve linear time and constant space complexity while handling strings with backspaces.

Statement

Given two strings s and t, return true if they produce the same result when typed into an empty text editor, where '#' represents a backspace character. Applying a backspace on an empty editor leaves it unchanged.

Note: Can you solve it in O(n)O(n) time and O(1)O(1) space?

Constraints:
