Build a DFA to accept Binary strings that starts or ends with “01”

WebA Finite Automata is a simple machine that recognizes patterns in the input string. If the input string contains the pattern defined by FA it accepts the string otherwise rejects it. For a particular input string, a machine can go to only 1 state in DFA but a machine can go to multiple states in NFA.
