A finite automata over the input alphabet {x,y} is given below. What does the following deterministic finite automata perform?
  • a)
    Accepts all the strings in which every y is followed by x.
  • b)
    Accepts all the strings whose second symbol from left hand side is x.
  • c)
    Accepts all the strings of length divisible by 3.
  • d)
    Accepts all the strings ending with a.
Correct answer is option 'B'. Can you explain this answer?

We can solve this ques by elimination.
a) is wrong bcoz strings like "xxy","xxyy" etc are accepted where y is not followed by x.
c) is wrong bcoz strings like "xx","yx","xxyy" are accepted which are not in multiple of 3.
d) is wrong bcoz it may end in both 'x' and 'y' as seen in above examples.
Only b) is correct bcoz if we take strings like "xy" or "yy" it directly goes to dead state D, so the 2nd letter from left ("xxy","xxyy","yx" etc) must always be 'x' to be acceptable by given DFA.
