int main() {
srand(time(0));
int A, B, n, c =0, z =0;
cin>>A>>B>>n;

int a[n], b[n];
for(int i = 0; i < n; i++){
    cin>>a[i];
}
for(int i = 0; i < n; i++){
    cin>>b[i];
}
for(int i = 0; i < n; i++){
    int x = rand() % (0 - n);
    while(1>0 == true){
        B = B - a[x];
        b[x] = b[x]-A;
        if(b[x]<=0){z++; break;}
        if((B <= 0)){break;}
    }
    if(z == n){ cout<<"Yes";}
    if((B <= 0)&&(z!=n)){ cout<<"NO"; break;}
