If the intersection of
Explanation of Solution
b)
Consider the above grammar to perform pairwise disjointness.
Find the First set for Right Hand Side of non-terminal symbol A.

- Study the grammar G: { S → a | aRb, R → b | bSa }. Which of the following strings is NOT generated by G? A. abb B. abaab C. ababbab D. None of the above since all 3 strings above can be generated by G.arrow_forwardConvert the following context-free grammar to Chomsky normal form. Then check to see if the following string would be accepted by this grammar using the CYK algorithm. Show your steps. String: aabbaac S → A A → aAb | B BcB | Aarrow_forwardPlease help 5.
