1425 - Constrained Subsequence Sum\. Hard Given an integer array `nums` and an integer `k`, return the maximum sum of a **non-empty** subsequence of that array such that for every two **consecutive** integers in the subsequence, `nums[i]` and `nums[j]`, where `i < j`, the condition `j - i <= k` is satisfied. A _subsequence_ of an array is obtained by deleting some number of elements (can be zero) from the array, leaving the remaining elements in their original order. **Example 1:** **Input:** nums = [10,2,-10,5,20], k = 2 **Output:** 37 **Explanation:** The subsequence is [10, 2, 5, 20]. **Example 2:** **Input:** nums = [-1,-2,-3], k = 1 **Output:** -1 **Explanation:** The subsequence must be non-empty, so we choose the largest number. **Example 3:** **Input:** nums = [10,-2,-10,-5,20], k = 2 **Output:** 23 **Explanation:** The subsequence is [10, -2, -5, 20]. **Constraints:** * 1 <= k <= nums.length <= 105 * -104 <= nums[i] <= 104
