1827 - Minimum Operations to Make the Array Increasing\.
Easy
You are given an integer array `nums` ( **0-indexed** ). In one operation, you can choose an element of the array and increment it by `1`.
* For example, if `nums = [1,2,3]`, you can choose to increment `nums[1]` to make `nums = [1, **3** ,3]`.
Return _the **minimum** number of operations needed to make_ `nums` _**strictly** **increasing**._
An array `nums` is **strictly increasing** if `nums[i] < nums[i+1]` for all `0 <= i < nums.length - 1`. An array of length `1` is trivially strictly increasing.
**Example 1:**
**Input:** nums = [1,1,1]
**Output:** 3
**Explanation:** You can do the following operations:
1) Increment nums[2], so nums becomes [1,1, **2** ].
2) Increment nums[1], so nums becomes [1, **2** ,2].
3) Increment nums[2], so nums becomes [1,2, **3** ].
**Example 2:**
**Input:** nums = [1,5,2,4,1]
**Output:** 14
**Example 3:**
**Input:** nums = [8]
**Output:** 0
**Constraints:**
* `1 <= nums.length <= 5000`
* 1 <= nums[i] <= 104
