Reverse Letters Only

Given a string `s`, reverse the string according to the following rules: - All the characters that are not English letters remain in the same position. - All the English letters (lowercase or uppercase) should be reversed. Return `s` after reversing it. ### Constraints - `1 <= s.length <= 100` - `s` consists of characters with ASCII values in the range `[33, 122]`. ### Input Format A single line containing the string `s`. ### Output Format Print the reversed string.
