#include <iostream>
using namespace std;
int main()
{
int m,n,k;
cout<<"enter m n k ";

cin >> m >> n >> k;


if ( m>0 && m<19 )
{
if ( k>1 && k<6 )
{
if ( n>0 && n<23 )
{
cout<<(m+k+n);

}
else
cout<<"enter n between 0 and 23"<<endl;
}
else
cout<<"enter k between 1 and 6"<<endl;

}
else
cout<<"enter m between 0 and 19"<<endl;
return 0;

}

What the answer to test:

    m    k    n
12    3    2    18

I got 53 and WA

Maybe, someone knows, what is it?

I'm pretty sure that testset for this problem doesn't contain maxitests with k=2 and n=22. Otherwise how could program that works about 20sec. on my computer get AC on timus???

#include<iostream>
using namespace std;
int main()
{
    int n,k,m,b;
    cin>>m;
    cin>>k;
    cin>>n;
    b=m+k+n;
    cout<<b;
   return 0;
}
