Give a CFG that generates the language L(a*b*c*) { anbncn | n is a non-negative integer }. This question is quite challenging; you will first need to devise a good strategy for how the CFG should work and then create the CFG to implement the strategy. You might want to do the other questions first. No messy writing please.

Step 1
First, we need to generate any number of 'a's. This can be done by the production rule S -> aS | ε. Show more…
