Solution in C++14 (GCC 5.4.1) (judge verdict: Wrong Answer)

#include<iostream>

using namespace std;

int main(){
    int A,B,max,C[3];
    cin>>A>>B;
    C[0]=A+B;
    C[1]=A-B;
    C[2]=A*B;

    max=0;

    for(int i=0;i<3;i++){
        if(C[i]>max){
            max=C[i];
        }
    }
    cout<<max<<endl;

    return 0;
