Given two strings `s` and `t`, return `true` if they are equal when both are typed into empty text editors. The character `#` means a backspace character.
Note that after backspacing an empty text, the text will continue to be empty.
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.
