Given an integer array
arr, partition the array into (contiguous) subarrays of length at most k. After partitioning, each subarray has its values changed to become the maximum value of that subarray.Return the largest sum of the given array after partitioning. Test cases are generated so that the answer fits in a 32-bit integer.
Examples
Example 1
Inputarr = [1,15,7,9,2,5,10], k = 3
Output84
Explanationarr becomes [15,15,15,9,10,10,10]
Example 2
Inputarr = [1,4,1,5,7,3,6,1,9,9,3], k = 4
Output83
Example 3
Inputarr = [1], k = 1
Output1
Constraints
1 <= arr.length <= 500
0 <= arr[i] <= 10^9
1 <= k <= arr.length
