Note: Not to be confused with pyscfg which appears to parse configurations into and out of YAML files. WebNov 26, 2024 · Step 1: Make an initial state “A”. The minimum possible string is 01 which is acceptable. For this, make the transition of 0 from state “A” to state “B” and then make the transition of 1 from state “B” to state “C” and notice this state “C” as the final state. Step 2: Now, we have designed the DFA that start with 01. fitfroor
