Suppose that a handle is a substring that matches a right hand side or production rule in the grammar and whose reduction to the non-terminal on the left hand side of that grammar rule is a step along the reverse of a right most derivation.
Question # 1:
Find the handles of the sentential forms occurring in the derivation of string “id + id * id” by the following grammar E → E+E | E*E | id
Question # 2:
Consider the following grammar and show the handle of each right sentential form for string (a, (a, a)). S → (L) | a L → L, S | S
