+<p>You are given an array <code>nums</code> consisting of <strong>positive</strong> integers.</p>
+
+<p>We call a subarray of <code>nums</code> <strong>nice</strong> if the bitwise <strong>AND</strong> of every pair of elements that are in <strong>different</strong> positions in the subarray is equal to <code>0</code>.</p>
+
+<p>Return <em>the length of the <strong>longest</strong> nice subarray</em>.</p>
+
+<p>A <strong>subarray</strong> is a <strong>contiguous</strong> part of an array.</p>
+
+<p><strong>Note</strong> that subarrays of length <code>1</code> are always considered nice.</p>
+
+<p>&nbsp;</p>
+<p><strong>Example 1:</strong></p>
+
+<pre>
+<strong>Input:</strong> nums = [1,3,8,48,10]
+<strong>Output:</strong> 3
+<strong>Explanation:</strong> The longest nice subarray is [3,8,48]. This subarray satisfies the conditions:
+- 3 AND 8 = 0.
+- 3 AND 48 = 0.
+- 8 AND 48 = 0.
+It can be proven that no longer nice subarray can be obtained, so we return 3.</pre>
+
+<p><strong>Example 2:</strong></p>
+
+<pre>
+<strong>Input:</strong> nums = [3,1,5,11,13]
+<strong>Output:</strong> 1
+<strong>Explanation:</strong> The length of the longest nice subarray is 1. Any subarray of length 1 can be chosen.
