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
