Suppose at state Q0, if 0 comes, the function call is made to Q1. First like DFA cover the inputs in the start There is slight change than DFA, we will include the higer bound and then we will go ahead with the actual input Means we will go on state A for input 'a'/'b' and then also we will go to state B on input 'a' As the string ends with 'a' and then if anything comes up we are not worried as it is not DFA. You could add a self-loop to q3 so that the automaton stays in q3 if it receives more 1s and 0s. In the column 1 you just write to what the state in the state column switches if it receives a 1. the table has 3 columns: state, 0, 1.
