Timer for Clash of Code
Statement
Goal
You have to implement a version of the timer in Clash of Code. The timer starts at 5:00 and runs towards 0:00. The timer stop time changes based on players joining.Here are the rules:
* Every time a player joins the clash, the timer stop time is set to
t - 256 / ( 2^(p - 1) )where t is current time in seconds and p is the number of players in the room before the new player joined.
* If the result is under 0:00, set it to 0:00.
* If a player joins at the same time the game is supposed to start, set the new timer stop time instead of starting the game.
For example:
At 5:00 the timer starts, and there is one player (the one who started the clash).
At 4:47 the second player joins -> set to start 256 seconds from now, at 0:31.
At 3:56 the third player joins -> set to start 128 seconds from now, at 1:48.
At 3:13 the fourth player joins -> set to start 64 seconds from now, at 2:09.
At 2:09, the game starts.
Output: 2:09
The game starts if:
* The timer reaches the time it is set to stop at, or
* The timer reaches zero and there is more than one player, or
* The clash room is filled (8 players in total, 7 have joined).
Input
First line: An integer n for the number of players who join the clash
The next n lines: Time stamps in the format m: ss (minutes and seconds) at which a player joins the clash
The next n lines: Time stamps in the format m
Output
Output the time stamp at which the game starts in the format m: ss.
If no one joined, outputNO GAME .
If no one joined, output
Constraints
n: Between 0 inclusive and 7 inclusive
Time stamps: Between 0:00 exclusive and 5:00 exclusive
