Predictive parsers are recursive descent parsers that need no backtracking and can be constructed for a class of grammars called LL (1). The first "L" in LL (1) indicates that, scanning the input from left to right. The second "L" in LL (1) signifies that, producing a leftmost derivation. The "1" in LL (1) indicates that, using one input symbol of lookahead at each step to make parsing action decisions. Like recursive descent, the LL (1) technique is top-down, goal oriented, and predictive. Consider the grammar G5: S → iEtSS′|a S′ → eS|ԑ E → bConstruct the LL (1) parsing table for the grammar G5 and use the LL (1)parsing table for the grammar G5 to check whether the grammar G5 is LL (1). Algorithm sheet: Algorithm for Constructing LL (1) Parsing Table Input: Grammar G.Output: Parsing table M.Method: For each production A → a of the grammar, do the following: Step 1: For each terminal "a" in ?????

Let ANTIPALINDROME be the language of all even-length strings over the alphabet {a,b} such that, for all i, the i-th letter from the start is different to the i-th letter from the end.

Eliminate left recursion in the following grammar.
Remove immediate left recursion from the following grammar: I. 4. G(N,TP.S): N= {S,A,B,C} T= {a,b,c,d,e,fh.g.k} S= {S} P: S- ScbaA | SdbaA SebaA | ABC A Ad | Ae | Bc B- aC | aB C- Cf | Cg | hk | ɛ %3D
The following given grammar is a left recursive grammar S Sbab balb The language generated by this grammar is of the following form: L= { ba(bab), b(bab)" | m,ne N} This left recursive grammar can be transformed to a right recursive grammar as follows: S → T -> This right recursive grammar is an LL( ) grammar.
3. Given the following BNF grammar: -> d c | cd -> a la -> b | b Use the top-down recursive descent method which we discussed in the class to implement a parser (i.e. tdrd.parser.py) in python3 for the above BNF grammar. The input data file name is given from the command line. You may assume that there is a space character between two terminals (e.g. a a adc b ) in the data file.
3. Given the following grammar: -> -> p I p -> q r -> t |t Use the method discussed in the class to implement a parser which recognizes the sentences generated by this grammar. So the query: s([p,p,q,r,t,t,t],[]). will return true.
