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. Examples of strings in this language include: ε, ab, ba, aabb, abab, baba, bbaa, aaabbb, ... Give a Context-Free Grammar for the language ANTIPALINDROME.
