Solution: Backspace String Compare
Understand how to use the two pointers technique to compare two strings containing backspace characters without reconstructing them. This lesson guides you through a step-by-step approach to traverse strings from right to left, handle backspaces, and achieve an efficient O(n) time and O(1) space solution for the backspace string compare problem.

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.
