Most asked AKTU PYQ questions from Unit 1

  1. Q3b. Check whether given grammar is ambiguous or not. If ambiguous then convert it into unambiguous grammar: E→E+E|E*E|id. (10 marks, 2023-24)
  2. Q2a. Explain in detail the process of compilation. Illustrate the output of each phase of compilation of the input “a=(b+c)*(b+c)*2”.. (10 marks, 2016-17)
  3. Q2a. Describe the relationship between finite state machines and regular expressions. Discuss how regular expressions are used in lexical analysis and pattern matching. (10 marks, 2023-24)
  4. Q3a. Given a regular expression a(b|c)*, construct the corresponding Nondeterministic Finite Automaton (NFA) that recognizes the language described by the regular expression. (10 marks, 2023-24)
  5. Q2a. Demonstrate the process of compilation with the help of following input: c = a*b+10 (10 marks, 2023-24)
  6. Q3a. Construct minimized DFA: (10 marks, 2023-24)
  7. Q3b. Explore the phases of compiler with a suitable example. (10 marks, 2023-24)
  8. Q2d. Construct the NFA and DFA for the following regular expression. (0+1)*(00+11)(0+1)* (10 marks, 2022-23)
  9. Q2a. Construct a DFA that accepts a language L over input alphabets ∑ = {a, b} such that L is the set of all strings starting with ‘aa’ or ‘bb’. (10 marks, 2022-23)
  10. Q2a. Explain in detail the process of compilation for the statement a=b+c*70. (10 marks, 2020-21)
