/**
 * 1790. Check if One String Swap Can Make Strings Equal
 * https://leetcode.com/problems/check-if-one-string-swap-can-make-strings-equal/
 * Difficulty: Easy
 *
 * You are given two strings s1 and 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.
 *
 * Return 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 false.
