Construct the parse tree for the string '((a)b)' using the CFG with rules S → (S) | a | b.
💡 Hint: Focus on the proper sequence of applying each rule according to the CFG.
Using the CFG: S → SS | (S) | a, derive the string 'a(a)a' and describe the resulting parse tree structure.
💡 Hint: Think of how each rule extends and connects to different terminal symbols.
