2789. Largest Element in an Array after Merge Operations

You are given a 0-indexed array nums consisting of positive integers. You can do the following operation on the array any number of times: - Choose an index i such that 0 <= i < nums.length - 1 and nums[i] <= nums[i + 1]. Replace the element nums[i + 1] with nums[i] + nums[i + 1] and delete the element nums[i] from the array. Return the value of the largest element that you can possibly obtain
