Ambiguous Grammars Question 3 [10 points be an ambiguous context-free grammar. We know that the length of S Mwis not always the same as the length of S → M w. 15/10] Consider the string abba. Create a context-free grammar that proves this point, and show the 2 different derivations of different length. ·15/10 If a context-free grammar is not LL(1) can it then be LR(1) without changing anything? Explain and/or give an example.
