自从上年的11月份参加过TC的比赛后，就再也没有参加了，因为它的输入输出格式比较难接受，还有它的页面字体比较小，看得我很辛苦...藉口藉口～～懒而已！不过以后我会尽量去参加的，为了提高自己的编程能力。
以 SRM 144 DIV 2 的 200 分题目为例，记录下两种输入输出格式吧。

Problem Statement |
|||||||||||||
|
|
Computers tend to store dates and times as single numbers which represent the number of seconds or milliseconds since a particular date. Your task in this problem is to write a method whatTime, which takes an int, seconds, representing the number of seconds since midnight on some day, and returns a string formatted as "<H>:<M>:<S>". Here, <H> represents the number of complete hours since midnight, <M> represents the number of complete minutes since the last complete hour ended, and <S> represents the number of seconds since the last complete minute ended. Each of <H>, <M>, and <S> should be an integer, with no extra leading 0's. Thus, if seconds is 0, you should return "0:0:0", while if seconds is 3661, you should return "1:1:1". |
