可以帮忙看看吗？C题

#include <iostream>
#include <cstdio>
#include <cmath>
#include <algorithm>

using namespace std;

int n,m,op;
double me = 1,tt = 1,x;

int main() {

    scanf("%d",&n);

    while(n--)
    {

        scanf("%d %lf",&op,&x);

        if(op == 1) me *= x;
        else me /= x;
    }

    scanf("%d",&m);

    while(m--)
    {

        scanf("%d %lf",&op,&x);

        if(op == 1) tt *= x;
        else tt /= x;

    }

    

    if(tt == me || fabs(tt - me <1e-9)) printf("YES");
    else printf("NO");



    return 0;
