I'd like to add that of the three algoritms mentioned so far (mergesort, quicksort and heap sort) only mergesort is stable. That is, the order does not change for those values which have the same key. In some cases this is desirable.

You can not make kernel-mode device drivers in C# as the runtime can't be safely loaded into ring0 and operate as expected.

You are correct an array is great for look ups. However modifications to the size of the array are costly.

in my opinion you should use this technique only if failure is a "normal part of operation" of your method / function, e.g. its as probable that a call suceeds as that it fails. If failure is a exceptional event, then you should use exception handling so your program can terminate as early and gracefully as possible. |

I think it depends on the library and database engine. Each one will execute the SQL differently, and there's no telling which one will be optimized. |
If you ever wish to make the query more general, perhaps substituting a parameter for the target country, then I'd go with your first example, as it requires only a single change. That's less to worry about getting wrong in the future. |
