Sorting and Time Conversion

  1. Initialize an empty list minutes to store time points in minutes.
  2. Convert each time point from HH:MM format to minutes since midnight and add to minutes list.
  3. Sort the minutes list.
  4. Initialize min_diff to a large value (e.g., float('inf')).
  5. Iterate through the sorted minutes list and calculate the difference between consecutive times, updating min_diff with the minimum value found.
  6. Calculate the difference between the first and last time points, considering the circular nature of the clock, and update min_diff if this difference is smaller.
  7. Return min_diff as the final result.
