Note π - This is a follow up question of Find Maximum Length of Non-Decreasing Subarray Part 1 π¦
You can choose any one index and change its value to any number that you like. What will be the longest non decreasing subarray now:
In the same example as before, the answer would now be:
ans = 6, [2 4 6 8 0 9], by changing 0 -> 8 so the subarray becomes non-decreasing.
1Example 1
Input
nums = [2, 4, 6, 8, 0, 9]
Output
6
Explanation
By changing the value at index 4 from 0 to 8, the array becomes [2, 4, 6, 8, 8, 9], which is non-decreasing. The length of this subarray is 6, which is the longest possible non-decreasing subarray after making one change.
Constraints
Limits and guarantees your solution can rely on.
