Reverse Only Letters
In this video, I solved the LeetCode problem "Reverse Only Letters" using the Two Pointer Approach. Problem: Given a string s, reverse only the letters in the string. All non-letter characters should remain in their original positions. Approach: We use two pointers: * left pointer from the start * right pointer from the end Steps: * If the left character is not a letter, move left forward * If the right character is not a letter, move right backward * If both characters are letters, swap them * Continue until both pointers meet This keeps all special characters, digits, and symbols in the same position while reversing only letters.
