You are given two strings
s2 of equal length. A string swap is an operation where you choose two indices in a string (not necessarily different) and swap the characters at these indices.
true if it is possible to make both strings equal by performing at most one string swap on exactly one of the strings. Otherwise, return
Input: s1 = "bank", s2 = "kanb" Output: true Explanation: For example, swap the first character with the last character of s2 to make "bank".
Input: s1 = "attack", s2 = "defend" Output: false Explanation: It is impossible to make them equal with one string swap.
Input: s1 = "kelb", s2 = "kelb" Output: true Explanation: The two strings are already equal, so no string swap operation is required.
1 <= s1.length, s2.length <= 100
s1.length == s2.length
s2consist of only lowercase English letters.
