【topcoder第一弹】 SRM 144 Div.2 whatTime

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, ifseconds is 0, you should return "0:0:0", while if seconds is 3661, you should return "1:1:1".

做topcoder还要现下客户端，外国服务器连的慢，就直接把页面内容粘过来了……

题目大意：给出秒数，转换成“时：分：秒”格式。

题目分析：水无坑，算法简单易懂。

code:

public class Time{public String whatTime(int seconds){int h,m;String ans;h=seconds/3600;seconds%=3600;m=seconds/60;seconds%=60;ans=""+h+":"+m+":"+seconds;return ans;}}

PS：准备期末考试，停了一段时间。从队长处得到topcoder的access，上来先水一发。

PSS：个人感觉topcoder写法较诡异……
