Sort the time according to the specified criteria.
The first line contains the number n (1≤n≤100). Then n times are given. Each time is given as three integers — hours (0 to 23), minutes (0 to 60), and seconds (from 0 to 60).
Print the times, sorted in nondecreasing order (time is also displayed in the form of three numbers, do not print the leading zeros).
