The universe of algorithm and data structures

Cosmos is your personal offline collection of every algorithm and data structure one will ever encounter and use in a lifetime. This provides solutions in a various languages spanning C, C++, Java, Python, Go and others.

This work is maintained by a community of hundreds of people and is a massive collaborative effort to bring the readily available coding knowledge offline.

Many coders ask me how to improve their own performances. I cannot say anything except "solve and review and prepare your library - Uwi Tenpen

Following is the high-level structure of cosmos:

• Backtracking
• Bit manipulation
• Computational geometry
• Data structures
• Divide conquer
• Dynamic programming
• Graph algorithms
• Greedy algorithms
• Mathematical algorithms
• Randomized algorithms
• Search
• Sorting
• String algorithms
• Unclassified 👻

Each type has several hundreds of problems with solutions in several languages spanning C, C++, Java, Python, Go and others.

This is a massive collaboration and to keep the quality intact and drive the vision in the proper direction, we have maintainers.

Maintainers are your friend forever. They are vastly different from moderators.

The task of maintainers is to review pull requests, suggest further quality additions and keep the work upto data with the current state of the world. 🌍
