+ * 1696. Jump Game VI
+ * https://leetcode.com/problems/jump-game-vi/
+ * Difficulty: Medium
+ *
+ * You are given a 0-indexed integer array nums and an integer k.
+ *
+ * You are initially standing at index 0. In one move, you can jump at most k steps forward without
+ * going outside the boundaries of the array. That is, you can jump from index i to any index in
+ * the range [i + 1, min(n - 1, i + k)] inclusive.
+ *
+ * You want to reach the last index of the array (index n - 1). Your score is the sum of all
+ * nums[j] for each index j you visited in the array.
+ *
+ * Return the maximum score you can get.
