Building Sierra Leone's programming community

Our mission

Programming is learned by writing code and getting fast, honest feedback. Salone Programming Contest gives students across Sierra Leone a place to practise C and Python against real test cases, compete in timed contests, and see how they measure up nationally — all from a browser, even on a modest connection.

How judging works

1. 1

   You submit source code

   Your code is stored with the problem, contest and language you chose.

2. 2

   The sandbox compiles and runs it

   Execution happens in an isolated sandbox with strict time and memory limits — never on your machine or ours.

3. 3

   Every test case is compared

   Output is trimmed of trailing whitespace and compared line by line against the expected output.

4. 4

   Points are awarded per passing test

   Partial credit is possible: each hidden test case carries its own points. Your best score per problem counts.

Contest rules

• Work individually unless a contest explicitly allows teams.
• Submissions after the contest end time are not scored.
• Read input from standard input and write to standard output.
• Copying another participant's solution results in disqualification.
• Practice submissions outside a contest never affect contest standings.
