Solution: Sorting
def reorderLogFiles(logs: List[str]) -> List[str]:
letter_logs, digit_logs = [], []
for log in logs:
new_log = log.split(" ", 1)
if new_log[1][0].isnumeric():
digit_logs.append(log)
else:
letter_logs.append((new_log[0], new_log[1]))
letter_logs.sort(key=lambda x: (x[1], x[0]))
sorted_letter_logs = [f"{key} {value}" for key, value in letter_logs]
return sorted_letter_logs + digit_logs
