Automata Theory Construct a regular expression for the set of bit strings in which every odd bit is 1. For example, these are in the language: 10 (OK: 1 in position 1) 111 (OK: 1 in positions 1 and 3) 10101 (OK: 1 in positions 1, 3, and 5) 101111 (OK: 1 in positions 1, 3, and 5) ϵ (OK: There are no odd positions) And these are not in the language: 0111 (BAD: position 1 is not a 1)...
