+<h2><a href="https://leetcode.com/problems/minimize-xor/">2429. Minimize XOR</a></h2><h3>Medium</h3><hr><p>Given two positive integers <code>num1</code> and <code>num2</code>, find the positive integer <code>x</code> such that:</p>
+
+<ul>
+	<li><code>x</code> has the same number of set bits as <code>num2</code>, and</li>
+	<li>The value <code>x XOR num1</code> is <strong>minimal</strong>.</li>
+</ul>
+
+<p>Note that <code>XOR</code> is the bitwise XOR operation.</p>
+
+<p>Return <em>the integer </em><code>x</code>. The test cases are generated such that <code>x</code> is <strong>uniquely determined</strong>.</p>
+
+<p>The number of <strong>set bits</strong> of an integer is the number of <code>1</code>&#39;s in its binary representation.</p>

+<p>&nbsp;</p>
+<p><strong class="example">Example 1:</strong></p>
+
+<pre>
+<strong>Input:</strong> num1 = 3, num2 = 5
+<strong>Output:</strong> 3
+<strong>Explanation:</strong>
+The binary representations of num1 and num2 are 0011 and 0101, respectively.
+The integer <strong>3</strong> has the same number of set bits as num2, and the value <code>3 XOR 3 = 0</code> is minimal.
+</pre>
+
+<p><strong class="example">Example 2:</strong></p>
+
+<pre>
+<strong>Input:</strong> num1 = 1, num2 = 12
+<strong>Output:</strong> 3
+<strong>Explanation:</strong>
+The binary representations of num1 and num2 are 0001 and 1100, respectively.
+The integer <strong>3</strong> has the same number of set bits as num2, and the value <code>3 XOR 1 = 2</code> is minimal.
