Please ASAP, it's important Design a CFG which recognizes the language L={ w | all the letters on the first half of w are the same, and the second half is a substring where no consecutive letters are the same } over the alphabet Σ={0,1,2}. Explain your derivation rules. Note: consecutive means two letters which follow each other, " no consecutive letters are the same" means you can't repeat letters, so you can't have "00", "11" or "22" on the second half.

I'm having a hard time with section 2.5 part B. Despite multiple attempts, I can't seem to get it right. To address part B of 2.5, the question from 2.4 is required. The issue pertains to pushdown automata, and it would be immensely helpful if you could provide a visual representation illustrating the process you used to arrive at your solution. I've included my incorrect answer for your reference. Could you assist me in pinpointing why my approach is flawed? My focus is solely on resolving the problem with question 2.5 part B. question for 2.5 2.5 Give informal descriptions and state diagrams of pushdown automata for the languages in Exercise 2.4. question for 2.4 that you will need for 2.5 2.4 Give context-free grammars that generate the following languages. In all parts, the alphabet Σ is {0,1}. b. {w| w starts and ends with the same symbol}
. Prove that the intersection of two context-free languages is not necessarily context-free. This is unlike the case of regular languages which are closed under intersections. Hint: Do something similar to what we did on Activity #21 to show something about two of the languages below and then use what we proved in class about the remaining language. Write several sentences to explain your reasoning. L₁ = {ww has the form a"b"c" for some whole numbers n and m} L2 = {ww has the form amb"c" for some whole numbers n and m} L3 = {w|w has the form a"b"c" for some whole number n}
