+<h2><a href="https://leetcode.com/problems/minimum-number-of-operations-to-make-array-continuous">2119. Minimum Number of Operations to Make Array Continuous</a></h2><h3>Hard</h3><hr><p>You are given an integer array <code>nums</code>. In one operation, you can replace <strong>any</strong> element in <code>nums</code> with <strong>any</strong> integer.</p>
+
+<p><code>nums</code> is considered <strong>continuous</strong> if both of the following conditions are fulfilled:</p>
+
+<ul>
+	<li>All elements in <code>nums</code> are <strong>unique</strong>.</li>
+	<li>The difference between the <strong>maximum</strong> element and the <strong>minimum</strong> element in <code>nums</code> equals <code>nums.length - 1</code>.</li>
+</ul>
+
+<p>For example, <code>nums = [4, 2, 5, 3]</code> is <strong>continuous</strong>, but <code>nums = [1, 2, 3, 5, 6]</code> is <strong>not continuous</strong>.</p>
+
+<p>Return <em>the <strong>minimum</strong> number of operations to make </em><code>nums</code><em> </em><strong><em>continuous</em></strong>.</p>
+
+<p>&nbsp;</p>
+<p><strong class="example">Example 1:</strong></p>
+
+<pre>
+<strong>Input:</strong> nums = [4,2,5,3]
+<strong>Output:</strong> 0
+<strong>Explanation:</strong>&nbsp;nums is already continuous.
+</pre>
+
+<p><strong class="example">Example 2:</strong></p>
+
+<pre>
+<strong>Input:</strong> nums = [1,2,3,5,6]
+<strong>Output:</strong> 1
+<strong>Explanation:</strong>&nbsp;One possible solution is to change the last element to 4.
+The resulting array is [1,2,3,5,4], which is continuous.
+</pre>
+
+<p><strong class="example">Example 3:</strong></p>
+
+<pre>
+<strong>Input:</strong> nums = [1,10,100,1000]
+<strong>Output:</strong> 3
+<strong>Explanation:</strong>&nbsp;One possible solution is to:
+- Change the second element to 2.
+- Change the third element to 3.
+- Change the fourth element to 4.
+The resulting array is [1,2,3,4], which is continuous.
