2023编程挑战赛原题

比完赛回来一搜才发现是原题

OK，源码如下

#include <iostream>

using namespace std;

int main ()
{
	int Time=0;
	cin>>Time;
	int Hour=0,Min=0,Sec=0;
	if(Time>=3600)
	{
		Hour=Time/3600;
		Time=Time%3600;	
	}
	if(Time>=60)
	{
		Min=Time/60;
		Time=Time%60;
	}
	Sec=Time/1;
	cout<<Hour<<":"<<Min<<":"<<Sec;
	return 0;
}
