You are given a 0-indexed integer array nums and an integer k. Your task is to perform the following operation exactly k times in order to maximize your score:
m from nums.m from the array.m + 1 to the array.m.Return the maximum score you can achieve after performing the operation exactly k times.
\n
Example 1:
\n\n\nInput: nums = [1,2,3,4,5], k = 3\nOutput: 18\nExplanation: We need to choose exactly 3 elements from nums to maximize the sum.\nFor the first iteration, we choose 5. Then sum is 5 and nums = [1,2,3,4,6]\nFor the second iteration, we choose 6. Then sum is 5 + 6 and nums = [1,2,3,4,7]\nFor the third iteration, we choose 7. Then sum is 5 + 6 + 7 = 18 and nums = [1,2,3,4,8]\nSo, we will return 18.\nIt can be proven, that 18 is the maximum answer that we can achieve.\n\n\n
Example 2:
\n\n\nInput: nums = [5,5,5], k = 2\nOutput: 11\nExplanation: We need to choose exactly 2 elements from nums to maximize the sum.\nFor the first iteration, we choose 5. Then sum is 5 and nums = [5,5,6]\nFor the second iteration, we choose 6. Then sum is 5 + 6 = 11 and nums = [5,5,7]\nSo, we will return 11.\nIt can be proven, that 11 is the maximum answer that we can achieve.\n\n\n
