Please help me, guys, I don't know what's the problem:(


#include <iostream>

using namespace std;


int lft[320], rght[320];

double timeleft[320], timeright[320];

double const eps = 0.0000001;

int main(){
    int n,m;
    cin >> n;
    for(int i = 1; i <= n; i++){
        cin >> lft[i];
        timeleft[i] = (lft[i] + 5.000)*9/50;
    }
    cin >> m;
    for(int i = 1; i <= m; i++){
        cin >> rght[i];
        timeright[i] = (rght[i]+5.000)*9/50 - 36.000/25;
    }

    double ans = 1000000000;

    if(lft[1] >= 8 && (rght[1] >= 16  || (rght[1] <= 3 && (rght[2] >= 16 || m == 1)))){
        cout << 0;
        return 0;
    }



    for(int i = 1; i <= n; i++){
        double cur = timeleft[i];
        bool b = 0;
        if(lft[i+1] - lft[i] >= 13 || lft[i+1] == 0){

            for(int j = 1; j <= n; j++){
                double temp = rght[j] - (cur + 36.000/25)*200.000/36;
                if(temp > -5 + eps && temp + eps < 8)
                    b = 1;
            }

        }
        else b = 1;
        if(!b && cur + eps < ans)
            ans = cur;
    }

    for(int i = 1; i <= m; i++){
        double cur = timeright[i];
        bool b = 0;
        if(rght[i+1] - rght[i] >= 13 || rght[i+1] == 0){

            for(int j = 1; j <= n; j++){
                double temp = lft[j] - cur*200.000/36;
                if(temp - eps > -5  && temp + eps < 8)
                    b = 1;
            }

        }
        else b = 1;
        if(!b && cur + eps < ans)
            ans = cur;
    }

printf("%.9f",ans);
return 0;
}
