EasyPython

Problem

Use the signature def sort_case_files(case_files):. Each case file is a dictionary containing a date field formatted as YYYY-MM-DD. Return a new list ordered from earliest to latest date. Do not modify the input list. If two case files have the same date, preserve their original order.

Constraints

  • 0 <= len(case_files) <= 10^4
  • Each case file is a dictionary containing a valid date string
  • Dates use the YYYY-MM-DD format
  • The input list must not be modified
  • Sorting is in ascending chronological order
