Given an array
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).
Input: nums = [4,2,3] Output: true Explanation: You could modify the first 4 to 1 to get a non-decreasing array.
Input: nums = [4,2,1] Output: false Explanation: You cannot get a non-decreasing array by modifying at most one element.
n == nums.length
1 <= n <= 104
-104 <= nums[i] <= 105
