Given an array of integers representing patient check-in times, write an efficient algorithm to find the peak operational hours for a clinic.

Treat each integer as an hour. Return all hours that occur most frequently, sorted in ascending order. The input contains at least one hour, and duplicate hours represent multiple check-ins.

Function: def peak_operational_hours(check_in_times):

Input is a list of integers. Output is a list of integers containing every hour tied for the maximum frequency.

Constraints

1 <= len(check_in_times) <= 100000
0 <= check_in_times[i] <= 23
Return all hours tied for the maximum frequency
Return the result in ascending order
