If you use LaTeX, you can simply include the source code into your document! Here are three examples with listings and minted. I’ve also included example PDF files. listings Minimal example Here [...]
3691 people are listed in the scoreboard, but 3851 tried the first problem. So I guess the number of contestants might even be higher. Problem 1 (Password Problem): Small Set: 3511/3851 users (91%) Large Set: 2329/3376 users (69%) Problem 2 (Kingdom Rush): Small Set: 1912/3466 users (55%) Large Set: 1617/1848 users (88%) Problem 3 (Cruise [...]
