Question

The operation changeleft replaces the leftmost symbol of any string by all other possible
symbols, that is, for all a e
changeleft(aw) = {bw :be I - {a}}.
Extending this to languages, we define
changeleft(L) = U changeleft(w).
WEL
(a) Letl be the language accepted by the finite automaton BELOW. Construct a finite
automaton for changeleft(L). Assume that { = {a, b, c).​

Answer 1

Answer:

The operation changeleft replaces the leftmost symbol of any string by all other possible

symbols, that is, for all a e

changeleft(aw) = {bw :be I - {a}}.

Extending this to languages, we define

changeleft(L) = U changeleft(w).

(a) Letl be the language accepted by the finite automaton BELOW. Construct a finite

automaton for changeleft(L). Assume that { = {a, b, c).
