Solution: Backspace String Compare

Explore how to compare two strings including backspace characters by traversing them from right to left using two pointers. Learn to identify visible characters without rebuilding strings, ensuring an O(n) time and O(1) space solution.

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?
