Just make new PR with an algorithm, data structures, ciphers or puzzle implementation. Language doesn't matter. Follow the structure: https://github.com/ZoranPandovski/al-go-rithms#contribution

If the implementation already exists follow the code structure and create new dir with e.g your name, 1, 2, or use your imagination 💥 🥇

The code from https://cp-algorithms.com/graph/push-relabel.html doesn't work.
Very easy to see that it is buggy, since the code doesn't use the target vertex t at all.

Hi friends, since many of you are starting to contribute for Hacktoberfest.

To not disallow beginners to contribute to the project, this issue can be taken up by anyone starting to learn data structures and algorithms.

You need to start solving the problems in the Hackerrank's Tracks and add your solutions in the branch named trackname in a new f

Need to write a set of tutorials detailing the various examples, in the style of the "simple-exercise" tutorial.

Description of the problem

Idea of using arrays for constructing binary trees originated from codezonediitj/pydatastructs#38 (comment) which uses arrays for constructing binary heaps.
The challenge is to make the change without breaking existing API. One appro
