Clash of Code

Clash of Code is a mode aimed at improving coding efficiency through racing other users to create a robust solution to a problem as quick as possible. There are three different modes available in Clash of Code: Fastest, Shortest and Reverse.

Fastest: This mode is to create a solution to a problem passing all validators as quick as possible.

Shortest: This mode is for creating a solution in the shortest number of characters possible.

Reverse: This mode provides an input and output only. The user must decipher the problem only from this information and create a solution as quick as they can.

Puzzles

Puzzles are a selection of problems split into different difficulty levels. The goal is to provide a solution that will pass hidden validators, to ensure a complete solution. The hidden validators will include general solutions as well as edge cases. Each problem is accompanied by tags releated to the problem, for example: BFS, Trie, Backtracking, Pathfinding, Cryptography, ... etc.
