C++ Standard Template Library in Practice - Bidirectional Iterators

The video tutorial explains bidirectional iterators, which allow traversing elements in both directions. It covers their properties, how they differ from forward iterators, and provides a C++ code example demonstrating their use. The tutorial also discusses the efficiency of pre-increment operators over post-increment operators and shows how to traverse a vector backward using bidirectional iterators. Finally, it demonstrates debugging techniques using GDB to analyze code execution.
