1330 - Reverse Subarray To Maximize Array Value.<p>Hard</p> <p>You are given an integer array <code>nums</code>. The <em>value</em> of this array is defined as the sum of <code>|nums[i] - nums[i + 1]|</code> for all <code>0 <= i < nums.length - 1</code>.</p> <p>You are allowed to select any subarray of the given array and reverse it. You can perform this operation <strong>only once</strong>.</p> <p>Find maximum possible value of the final array.</p> <p><strong>Example 1:</strong></p> <p><strong>Input:</strong> nums = [2,3,1,5,4]</p> <p><strong>Output:</strong> 10</p> <p><strong>Explanation:</strong> By reversing the subarray [3,1,5] the array becomes [2,5,1,3,4] whose value is 10.</p> <p><strong>Example 2:</strong></p> <p><strong>Input:</strong> nums = [2,4,9,24,2,1,10]</p> <p><strong>Output:</strong> 68</p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= nums.length <= 3 * 10⁴</code></li> <li><code>-10⁵ <= nums[i] <= 10⁵</code></li> </ul>
