The UVa OJ was created in 1995 by Miguel Ángel Revilla, a mathematician teaching algorithms at the University of Valladolid in Spain. Ciriaco García de Celis, an informatics student at the University of Valladolid, implemented the first version of the judge using Bash, and then developed and maintained it for more than eight years.
In C++, the Standard Template Library (STL) provides the set template class, which is typically implemented using a binary search tree (e.g. red–black tree); SGI's STL also provides the hash_set template class, which implements a set using a hash table. C++11 has support for the unordered_set template class, which is implemented using a hash ...
