We are given hours, a list of the number of hours worked per day for a given employee.
A day is considered to be a tiring day if and only if the number of hours worked is (strictly) greater than 8.
A well-performing interval is an interval of days for which the number of tiring days is strictly larger than the number of non-tiring days.
Return the length of the longest well-performing interval.
 
Example 1:
Input: hours = [9,9,6,0,6,6,9]
Output: 3
Explanation: The longest well-performing interval is [9,9,6].

 
Constraints:

1 <= hours.length <= 10000
0 <= hours[i] <= 16
