比赛的时候交上去评测爆0 赛后自己又提交了一遍却对了一个点 已知hack数据为：

10
22 32 2
32 240 1
34 3 2
67 7 1
83 7 1
39 600 2
86 810 2
61 24 1
4 2 2
95 810 2

正确输出

2221343/226800

实际输出

2533193/226800

代码

#include<bits/stdc++.h>
using namespace std;
int main(){
	long long n;
	cin>>n;
	long long s,d,calc;
	int ansup=1,ansdown=1;
	int cc;
	cin>>ansup>>ansdown>>cc;
	for(int i=1;i<n;i++){
		cin>>s>>d>>calc;
		if(calc==1){
			ansup=ansup*d+s*ansdown;
			ansdown=ansdown*d;
			int maxx=__gcd(abs(ansup),abs(ansdown));
			ansup/=maxx;
			ansdown/=maxx;
		}else{
			ansup=ansup*d-s*ansdown;
			ansdown=ansdown*d;
			int maxx=__gcd(abs(ansup),abs(ansdown));
			ansup/=maxx;
			ansdown/=maxx;
		}
	}
	if(ansup%ansdown==0){
		cout<<ansup/ansdown;
		return 0;
	}
	int maxx=__gcd(abs(ansup),abs(ansdown));
	ansup/=maxx;
	ansdown/=maxx;

}
