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.
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.
\r\n
Example 1:
\r\n\r\n\r\nInput: nums = [1,1,1]\r\nOutput: 3\r\nExplanation: You can do the following operations:\r\n1) Increment nums[2], so nums becomes [1,1,2].\r\n2) Increment nums[1], so nums becomes [1,2,2].\r\n3) Increment nums[2], so nums becomes [1,2,3].\r\n\r\n\r\n
Example 2:
\r\n\r\n\r\nInput: nums = [1,5,2,4,1]\r\nOutput: 14\r\n\r\n\r\n
Example 3:
\r\n\r\n\r\nInput: nums = [8]\r\nOutput: 0\r\n\r\n\r\n
\r\n
Constraints:
\r\n\r\n1 <= nums.length <= 50001 <= nums[i] <= 104给你一个整数数组 nums （下标从 0 开始）。每一次操作中，你可以选择数组中一个元素，并将它增加 1 。
nums = [1,2,3] ，你可以选择增加 nums[1] 得到 nums = [1,3,3] 。请你返回使 nums 严格递增 的 最少 操作次数。
我们称数组 nums 是 严格递增的 ，当它满足对于所有的 0 <= i < nums.length - 1 都有 nums[i] < nums[i+1] 。一个长度为 1 的数组是严格递增的一种特殊情况。
\n\n
示例 1：
\n\n输入：nums = [1,1,1]\n输出：3\n解释：你可以进行如下操作：\n1) 增加 nums[2] ，数组变为 [1,1,2] 。\n2) 增加 nums[1] ，数组变为 [1,2,2] 。\n3) 增加 nums[2] ，数组变为 [1,2,3] 。\n\n\n
示例 2：
\n\n输入：nums = [1,5,2,4,1]\n输出：14\n\n\n
示例 3：
\n\n输入：nums = [8]\n输出：0\n\n\n
