Its a very simple problem just think really as a cricket math and analyze my code snippet.
cin>>p>>m>>n;
if(n>=p-1)
{
// then p balls will be bowled
k=(p-1)/m;
if(k<0)
k=0;
if(2+km<=p)
cout<<2+km<<endl;
else
{
cout<<2+km-m<<endl;
}
}
else
{
r=n+2;
if(n%m==0)
{
k=(n-1)/m;
if(k<0)
k=0;
if(2+km<=p)
cout<<2+km<<endl;
else
{
cout<<2+km-m<<endl;
}
}
else
{
cout<<r<<endl;
}
}
