Virtual Gate Test Series: Theory Of Computation - Context Sensitive Grammar
How can L(G) be regular? If we derive bSb --> bAcAb, now we have Ab-->b but we do not have the production bA since G is all production except last. So there is no production for A or bA. How can we go further?

General syllabus doubt
Hello, The gate 2018 syllabus explicitly mentions regular languages, context free languages and turing machines. It does not say anything about context sensitive languages and linear bounded automata..How much of these topics should i study?..definitions? closure properties?
