Cosmos is a crowd-sourced offline collection of every algorithm and data structure one will ever encounter and use in a lifetime. This provides solutions in various languages spanning C, C++, Java, JavaScript, Swift, 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.

Over 700 contributors have contributed to this mission and this acts as a data-store to other sister projects.
