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
