Question: Among the solutions that contain files within the repository needing the longest processed time to download, how many of them doesn't need to be
compiled if user wants to implement it?
SQL: SELECT COUNT(T2.RepoId) FROM Repo AS T1 INNER JOIN Solution AS T2 ON T1.Id = T2.RepoId WHERE T1.ProcessedTime = ( SELECT MAX(ProcessedTime) FROM Repo ) AND T2.WasCompiled = 1
