Problem Statement

You are given a 0-indexed integer array nums. You can perform any number of operations, where each operation involves selecting a subarray of the array and replacing it with the sum of its elements. For example, if the given array is [1,3,5,6] and you select subarray [3,5] the array will convert to [1,8,6]. Return the maximum length of a non-decreasing array that can be made after applying operations. A subarray is a contiguous non-empty sequence of elements within an array.
