Kode Konudrums
By cauchyk, 13 years ago, In English
Kode Konundrums is a technical event conducted as a part of Threads, the techfest at IIIT Hyderabad's Felicity. This event is a fusion of puzzles and programming. The main idea is to use programming to solve riddles which are difficult or can't be solved otherwise. Knowledge of scripting languages like Python, Perl, Bash, PHP or C, Java.. whatever, will be useful.
