How helan-rajpurohit/dsa works

This repository is a collection of standalone C and C++ data-structure and algorithm exercises, rather than one integrated application. The typical interaction is a user entering values or choosing menu operations in a console program, which then searches, transforms, or updates an in-memory structure and prints results. The graph groups the exercises by subject and preserves the five CORE MODULES. Most examples are independent; the provided excerpts do not establish links between them, so no cross-example workflow is implied.
