+<h2><a href="https://leetcode.com/problems/longest-subarray-with-maximum-bitwise-and">2419. Longest Subarray With Maximum Bitwise AND</a></h2><h3>Medium</h3><hr><p>You are given an integer array <code>nums</code> of size <code>n</code>.</p>
+
+<p>Consider a <strong>non-empty</strong> subarray from <code>nums</code> that has the <strong>maximum</strong> possible <strong>bitwise AND</strong>.</p>
+
+<ul>
+	<li>In other words, let <code>k</code> be the maximum value of the bitwise AND of <strong>any</strong> subarray of <code>nums</code>. Then, only subarrays with a bitwise AND equal to <code>k</code> should be considered.</li>
+</ul>
+
+<p>Return <em>the length of the <strong>longest</strong> such subarray</em>.</p>
+
+<p>The bitwise AND of an array is the bitwise AND of all the numbers in it.</p>
+
+<p>A <strong>subarray</strong> is a contiguous sequence of elements within an array.</p>
+
+<p>&nbsp;</p>
+<p><strong class="example">Example 1:</strong></p>
+
+<pre>
+<strong>Input:</strong> nums = [1,2,3,3,2,2]
+<strong>Output:</strong> 2
+<strong>Explanation:</strong>
+The maximum possible bitwise AND of a subarray is 3.
+The longest subarray with that value is [3,3], so we return 2.
+</pre>
+
+<p><strong class="example">Example 2:</strong></p>
+
+<pre>
+<strong>Input:</strong> nums = [1,2,3,4]
+<strong>Output:</strong> 1
+<strong>Explanation:</strong>
+The maximum possible bitwise AND of a subarray is 4.
+The longest subarray with that value is [4], so we return 1.

+	<li><code>1 &lt;= nums.length &lt;= 10<sup>5</sup></code></li>
+	<li><code>1 &lt;= nums[i] &lt;= 10<sup>6</sup></code></li>
