Consider any DFA for the language, and let 110, 101 be its states after reading 110, 101 (respectively). 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. The best answers are voted up and rise to the top, Not the answer you're looking for? Design FA with = {0, 1} accepts even number of 0's and even number of 1's. So you do not need to run two automata in parallel, but rather can run them sequentially. Example 6: Design a FA with = {0, 1} accepts the strings with an even number of 0's followed by single 1.
