    665 - Non-decreasing Array.

    Medium

    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:

    • n == nums.length

    • <code>1 <= n <= 10<sup>4</sup></code>

    • <code>-10<sup>5</sup><= numsi<= 10<sup>5</sup></code>
