Това е моят недописан код, колеги. 50/100. Моля ви да ми помогнете с вашата логика, крашва ми когато някой от братята не е работил тоест въведа 0 в конзолата.

#include <iostream>

#include <cmath>

using namespace std;

int main()

{

    double timeA, timeB, timeC, timeD ;

    cin >> timeA >> timeB >> timeC >> timeD;

    double haveTime = timeA+timeB+timeC+timeD;

    haveTime =  haveTime / ( haveTime / timeA + haveTime / timeB + haveTime / timeC );

    haveTime = haveTime+ haveTime * 0.15 ;

        cout.setf( ios::fixed );

        cout.precision( 2 );

        cout << "Cleaning time: "<< haveTime << endl;

    if ( haveTime >= 0 && haveTime <= timeD ) {

        cout.setf(ios::fixed);

        cout.precision( 0 );

        cout << "Yes, there is a surprise - time left " <<"-> " << floor(timeD - haveTime) << " hours." << endl;

    }else if ( haveTime >=0 && haveTime >= timeD) {

        cout.setf ( ios::fixed );

        cout.precision( 0 );

        cout << "No, there isn't a surprise - shortage of time "<<"-> " << floor(haveTime + timeD) << " hours." << endl;

   }

return 0 ;
