The request
“A DFA over {0, 1} that accepts strings with an even number of 1s. Two states, Even and Odd; Even is the start state and the accepting state.”
Then tryChange it to accept an odd number of 1sAdd a dead state for any other symbol
What is in this drawing
Read the decisions behind it.
01
Marking the accepting state with a note instead of a final state
02
Using self-transitions to handle 0 inputs without state change
When teaching or visualizing deterministic finite automata, particularly simple pattern matching for parity of a symbol.
