About LeechanX/Data-Structures-and-Algorithms-in-C
A comprehensive collection of fundamental data structures and algorithms implemented in pure C. This open-source repository covers sorting, linked lists, stacks, queues, trees with applications, graph algorithms, string matching, backtracking, disjoint sets, and more. Each implementation is hand-coded, making it an excellent resource for learning and reference in academic assignments and interview preparation.

FAQ
What data structures and algorithms are included?
The repository includes sorting, linked lists, stacks, queues, trees, graph algorithms, string matching, backtracking, disjoint sets, maps, priority queues, and more, all implemented in pure C.
Is this repository still actively maintained?
The repository has a history of commits but recent activity is not evident. It is a stable reference implementation rather than a frequently updated project.
Can I use these implementations in my own projects?
Yes, the code is publicly available on GitHub. You can fork, clone, and use it under the license terms of the repository (implied to be open source).
