844. Backspace String Compare
Easy
10 Points
Two Pointers
String
Stack
Simulation
Given two strings s and t, return true if they are equal when both are typed into empty text editors. '#' means a backspace character.
Note that after backspacing an empty text, the text will continue empty.
Examples
Example 1
Input: s = "ab#c", t = "ad#c"
Output: true
Explanation: Both s and t become "ac".
Example 2
Input: s = "ab##", t = "c#d#"
Output: true
Explanation: Both s and t become "".
Example 3
Input: s = "a#c", t = "b"
Output: false
Explanation: s becomes "c" while t becomes "b".
Constraints
1 <= s.length, t.length <= 200
s and t only contain lowercase letters and '#' characters.
Follow Up
Can you solve it in O(n) time and O(1) space?
