Tags examples: Conditions, Graphs, Loops...
NB: Assess the difficulty based on the difficulty of existing puzzles, not on your ability to solve the puzzle.
Clash of Code
Clash of Code puzzles are simple In/Out puzzles specially created for short multiplayer battles. They're aimed to be solved in less than 15 minutes.
A Clash of Code puzzle must have at least 1 puzzle mode:
- Fastest: the most classic mode; the first player who passes all test cases wins.
- Shortest: also known as "code golf"; the first player who passes all test cases with the least number of character wins.
- Reverse: same as fastest but the players should guess what to do (the statement is hidden, only tests are shown); the first player who guesses what to do and passes all test cases wins. No need to write a statement for a reverse-only CoC then
There are no tags nor difficulty associated with a Clash of Code puzzle.
