         temp = (p - (d1-d2)*v2);
        day = ceil(temp/(float)(v1+v2)); // 
        cout<<day+(max(d1,d2))-1;
    }
    else if (d2>d1){
         temp = (p - (d2-d1)*v1);
        day = ceil(temp/(float)(v1+v2));
        cout<<day+(max(d1,d2))-1;
    }
    else{
        day = ceil(p/(float)(v1+v2));
        cout<<day+d1-1;
