Non-decreasing Array
Given an array nums with n integers, your task is to check if it could become non-decreasing by modifying at most one element.
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
- 1 <= n <= 10^4
- -10^5 <= nums[i] <= 10^5
