topcoder 的一些输入输出格式
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". | ||||||||||||

JAVA 版
public class Time{
public String whatTime(int seconds){
int h = seconds / 3600;
int m = (seconds % 3600) / 60;
int s = seconds % 3600 - m * 60;
return h + ":" + m + ":" + s;
}
}
C++ 版
#include <iostream>
using namespace std;
class Time{
public:
string whatTime(int seconds)
{
int h = seconds / 3600;
int m = (seconds % 3600) / 60;
int s = seconds % 3600 - m * 60;
char buf[40];
sprintf(buf, "%d:%d:%d", h, m, s);
return string(buf);
}
};
