The Hungarian Algorithm is a classic approach to solve the Maximum Bipartite Matching problem. In a bipartite graph, it identifies the largest set of edges such that each vertex is connected to at most one adjacent vertex. To illustrate its operation, consider a bipartite graph with left vertices (tasks: A, B, C, D) and right vetrices (workers: ...

An iterator is an object that enables traversal through a collection of elements, one at a time, in a forward-only manner. It does not support backward movement or random access. In Python, iterators implement two essential methods: __iter__() and __next__(). Built-in types such as lists, tuples, and strings are inherently iterable and can be c ...
