Non-decreasing Array

You are given an array nums with n integers, your task is to check if it could become non-decreasing by modifying at most one element.

We define an array is non-decreasing if nums[i] <= nums[i + 1] holds for every i (0-based) such that (0 <= i <= n - 2).

Example 1:

Input: nums = [4,2,3]

Output: true

Explanation: You could modify the first 4 to 1 to get a non-decreasing array.

Example 2:

Input: nums = [4,2,1]

Output: false

Explanation: You cannot get a non-decreasing array by modifying at most one element.

Constraints:

• 1 <= nums.length <= 10,000
• -100,000 <= nums[i] <= 100,000
