+<h2><a href="https://leetcode.com/problems/check-if-one-string-swap-can-make-strings-equal">1915. Check if One String Swap Can Make Strings Equal</a></h2><h3>Easy</h3><hr><p>You are given two strings <code>s1</code> and <code>s2</code> of equal length. A <strong>string swap</strong> is an operation where you choose two indices in a string (not necessarily different) and swap the characters at these indices.</p>
+
+<p>Return <code>true</code> <em>if it is possible to make both strings equal by performing <strong>at most one string swap </strong>on <strong>exactly one</strong> of the strings. </em>Otherwise, return <code>false</code>.</p>
+
+<p>&nbsp;</p>
+<p><strong class="example">Example 1:</strong></p>
+
+<pre>
+<strong>Input:</strong> s1 = &quot;bank&quot;, s2 = &quot;kanb&quot;
+<strong>Output:</strong> true
+<strong>Explanation:</strong> For example, swap the first character with the last character of s2 to make &quot;bank&quot;.
+</pre>
+
+<p><strong class="example">Example 2:</strong></p>
+
+<pre>
+<strong>Input:</strong> s1 = &quot;attack&quot;, s2 = &quot;defend&quot;
+<strong>Output:</strong> false
+<strong>Explanation:</strong> It is impossible to make them equal with one string swap.
+</pre>
+
+<p><strong class="example">Example 3:</strong></p>
+
+<pre>
+<strong>Input:</strong> s1 = &quot;kelb&quot;, s2 = &quot;kelb&quot;
+<strong>Output:</strong> true
+<strong>Explanation:</strong> The two strings are already equal, so no string swap operation is required.
+</pre>
+
+<p>&nbsp;</p>
+<p><strong>Constraints:</strong></p>
+
+<ul>
+	<li><code>1 &lt;= s1.length, s2.length &lt;= 100</code></li>
+	<li><code>s1.length == s2.length</code></li>
+	<li><code>s1</code> and <code>s2</code> consist of only lowercase English letters.</li>
