SPOJable

SPOJable is a term used within the competitive programming community to describe problems that are suitable for submission to the Sphere Online Judge (SPOJ). SPOJ is a platform that hosts a vast collection of programming challenges that users can solve and submit their solutions to. A problem is considered "SPOJable" if it aligns with the typical characteristics of problems found on SPOJ, such as having a clear problem statement, well-defined input and output formats, and a scope that can be solved within reasonable time and memory limits using common programming languages.

The term often implies that a problem is well-posed and has a unique, algorithmic solution that can be verified by an automated judge. Many competitive programmers engage in the process of creating or adapting problems to fit the SPOJ format, making them available for others to practice and hone their skills. When a problem is referred to as SPOJable, it suggests it would be a good addition to the SPOJ platform, contributing to its extensive library of algorithmic challenges. This can involve designing new problems from scratch or reformatting existing ones to meet SPOJ's specific requirements.
