BINCLOCK - Binary clock |
| Wersja polska | English version |
John found on the internet a specific type of clock which is called binary clock. He got interested in those clocks but he is not sure if he can change normal hour to binary format, so he asked you to write a program which would check whether he made it correctly or not.
Explanation of binary clock: http://en.wikipedia.org/wiki/Binary_clock
Input
The first line of the standard input contains one integer t (t<101) which is the number of test cases.
In each of the next t tests there are 24 digits (four lines with 6 digits in each of them) which represent the binary clock. There is one blank line after each test.
Output
One line with hour in following format: hour:min:sec or ERROR if time is incorrect.
Example
Input:3
000000
000000
000000
010101000000
010101
001011
100110000001
Output:
000001
000001
000001
01:01:01
14:25:36

Apart from this challenge, where I spent some time probing for holes in the testcases, ISPRIME had a big hole: no Fermat pseudoprimes, so one could use the very simple Fermat pseudoprimality test. But you fixed that some time ago :-) Last edit: 2011-02-27 19:57:41 |

It's easy to miss. No. But it's a good idea! I suggested that on spoj.pl/forum. Last edit: 2011-02-27 18:42:35 |

No problem, part of the challenge is finding holes in the testcases I guess ;-) By the way, is there a way to get email notification when a rejudge happens? It's easy to miss. Last edit: 2011-02-27 18:07:16 |

Thanks to zorro (kokosowo) who told me that tests are weak, I added 35 more tests and made rejudge. That's why some AC got WA. Please accept my apology for Your inconvenience. For my excuse I can just say that it was one of my first tasks. Last edit: 2011-02-27 16:00:12 |

It's OK now. (But my solution does not need a trailing empty line anymore, found a better way :) |

Is it now ok? It was because SPOJ somehow delete the last endline if it's the last char. I added second endline so that there's still one left at the end. |

The last testcase lacks an empty line at the end (not the displayed input, but the one actually passed to the program). Last edit: 2011-01-01 23:18:22 |

So why do You keep using IE? On Firefox, Opera and Google Chrome it looks ok. |

Still looks the same (pesky IE). |

That was my second idea in case the first one doesn't work. Is it ok now? |
