Among the solutions that contain files within the repository followed by over 1000 people, how many of them can be
implemented without needs of compilation?
followed by over 1000 people refers to Forks >1000; can be
implemented without needs of compilation refers to WasCompiled = 1;
SELECT COUNT(T2.RepoId) FROM Repo AS T1 INNER JOIN Solution AS T2 ON T1.Id = T2.RepoId WHERE T1.Forks > 1000 AND T2.WasCompiled = 1
