Description

Given two strings s1 and s2 of equal length, a string swap picks two positions in one string and swaps their characters. Return true if at most one such swap on exactly one string can make s1 equal s2.

Example 1:

Input: s1 = "bank", s2 = "kanb"

Output: true

Explanation: For example, swap the first character with the last character of s2 to make "bank".

Example 2:

Input: s1 = "attack", s2 = "defend"

Output: false

Explanation: It is impossible to make them equal with one string swap.

Example 3:

Input: s1 = "kelb", s2 = "kelb"

Output: true

Explanation: The two strings are already equal, so no string swap operation is required.
