Data Structures and Algorithms
The repository is pedagogical, esp. with cross-references in C++, Java and Python, while addition of libraries for real-world problems will be considered.
It also worths to see Simultaneous implementations (in C, C++, Java, Python, etc.) from https://www.geeksforgeeks.org/.
