利用二维数组求得的

#include<iostream>
using namespace std;
int main(){
int a, b, food[3][2], times;
bool flag;
cin>>a>>b;
for (int i=0; i<3; i++){
for (int j=0; j<2; j++){
cin>>food[i][j];
}
}
for (int i=0; i<3; i++){
if (food[i][1]<=b){
if (a%food[i][0]!=0){
times=a/food[i][0]+1;

        }
        if (times*food[i][0]>=a&&times*food[i][1]<=b){
            flag = true;
            break;
        } else{
            flag=false;
        }
    }
}
if (flag==true){
    cout<<"YES";
} else{
    cout<<"NO";
}
return 0;

}
