2. Consider the following context free grammar with terminals (), +, id, num, and starting symbol S. S (ST) F-id Fnum a. Compute the first and follow set of all non-terminals (use recursion or iteration, show all the steps) Show step-by-step (the parsing tree) how the following program is parsed: (num+num+id)) b.
Question 1. (15 points) Consider the following LL (1) grammar with starting symbol S s→(ST) F → id F → num a) Compute the First and Follow sets of all non-terminals (5 points) b) Construct the LL (1) parsing table for the grammar (5 points) c) Show step-by-step (content of stack and input string, as well as the production taken) how the following string is parsed: ((20+30 + a)) (5 points)
Consider following note that are terminals. E rightarrow e + t | t t rightarrow ID | j x rightarrow e, E | E Eliminate left Then perform left factoring for the grammar Compute the first set for all symbols in the grammar Compute the follow set for non-terminal in the grammar. Can you please explain how to get first follow set? Thanks.
