Interview Question for Financial Software Developer at Bloomberg L.P.:

I think that:
template<class T1; class T2; class T3> Should use , not ; between the types here

Tutorial Example:
template <class T, class U>
T GetMin (T a, U b)
{
  return (a<b?a:b);
}

I think you cannot return an int since the parameter is type T, you do not know if it is an int, so you must return a type T.

Actually returning an int could work in some cases. Either the result can be implicitly converted to int or there is a conversion operator defined.
