Reverse Only Letters

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.

Example 1
Inputs = "ab-cd"
Output"dc-ba"
The letters in ab-cd are reversed while the hyphen remains in the same position.
Example 2
Inputs = "a-bC-dEf-ghIj"
Output"j-Ih-gfE-dCba"
The letters are reversed across the string while each hyphen remains in its original position.

Constraints

  • 1 <= s.length <= 100
  • s consists of characters with ASCII values in the range [33, 122].
  • s does not contain '"' or '\'.
