Consider these examples: (1) A -> Aq (direct) (2) A -> Bq B -> Ar (indirect)

In this case order would be A < B < C, and possible paths for recursion of non-terminal C would be. C=> A => Cd and. C=> B => Ce so new rules for C would be. C=> Cd Ce f now you can simply just remove direct left ...

Indirect recursion: When function calls another function and that function calls the calling function, then this is called indirect recursion.
WebRecursion is a separate idea from a type of search like binary. Binary sorts can be performed using iteration or using recursion. There are many different implementations for each algorithm.
