2439\. Minimize Maximum of Array

Medium

You are given a **0-indexed** array `nums` comprising of `n` non-negative integers.

In one operation, you must:

*   Choose an integer `i` such that `1 <= i < n` and `nums[i] > 0`.
*   Decrease `nums[i]` by 1.
*   Increase `nums[i - 1]` by 1.

Return _the **minimum** possible value of the **maximum** integer of_ `nums` _after performing **any** number of operations_.

**Example 1:**

**Input:** nums = [3,7,1,6]

**Output:** 5

**Explanation:** One set of optimal operations is as follows: 
1. Choose i = 1, and nums becomes [4,6,1,6]. 
2. Choose i = 3, and nums becomes [4,6,2,5].
3. Choose i = 1, and nums becomes [5,5,2,5]. 

The maximum integer of nums is 5. It can be shown that the maximum number cannot be less than 5. 

Therefore, we return 5.

**Example 2:**

**Input:** nums = [10,1]

**Output:** 10

**Explanation:** It is optimal to leave nums as is, and since 10 is the maximum value, we return 10.

**Constraints:**

*   `n == nums.length`
*   2 <= n <= 105
*   0 <= nums[i] <= 109
