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

\n\n

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).

\n\n

 

\n

Example 1:

\n\n
\nInput: nums = [4,2,3]\nOutput: true\nExplanation: You could modify the first 4 to 1 to get a non-decreasing array.\n
\n\n

Example 2:

\n\n
\nInput: nums = [4,2,1]\nOutput: false\nExplanation: You can't get a non-decreasing array by modify at most one element.\n
