WebFor full credit your DFA must have no more than five states. Common Mistake: DFA not accepting strings in the form of 1*0*1*0*; b. Draw the state diagram of the NFA that recognizes the language L ={w ∈Σ* w i s a pal i ndr ome of l e ng t h 4} For full credit your NFA should have no more than fifteen states and the minimal number WebFeb 8, 2024 · odd number of a's, even number of b's. odd number of a's, odd number of b's (target state) (aa+bb)* is state invariant: the state before the match is the same as the state after the match. (ab+ba) swaps state 1 with state 4 and vice versa (and state 2 with state 3 and vice versa, but we're not interested in that)

Even number of a's, even number of b's (say q 0) … WebDFA String Examples. Let string is w, Number of a (w) mod 2 = 0 and Number of b (w) mod 2 = 0. This means number of a should be divisible by 2 as well as number of b should also be divisible by 2.
