Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
Please add separate tags for algorithms, for instance "Trees", "Graph", "Dynamic Programming" and so on so that it would be easier to find practice problems while learning.
A lesson for me and a hint for future fellas: "conditions must be met for a valid experiment" means it's OUR responsibility to check the validity of inputs! (I'm not native English speaker so such a problem might be only an issue for me)
