Given a non-negative integer array and an integer m, you need to divide the array into m non-empty contiguous sub-arrays. An algorithm is designed to minimize the maximum value of each of these m arrays.Attention:The array length n satisfies the following conditions:1≤n≤10001≤m≤min (N)Example:Input:Nums = [7,2,5,10,8]m = 2Output:18Explain:There are four ways to divide nums into 2 sub-arrays.The best way is to divide it into [7,2,5] and [10,8],Because at this point the maximum value for each of t
