Question: PLC: Design a state diagram to recognize escape sequence in Java, which are defined by the following BNF rules: EscapleSequence : b t f

PLC:

Design a state diagram to recognize escape sequence in Java, which are defined by the following BNF rules:

EscapleSequence:

\b \t

\ | \\ OctalEscape

OctalEscape:

\OctalDigit

\OctalDigit OctalDigit

\ZeroToThree OctalDigit OctalDigit

OctalDigit: one of 0 1 2 3 4 5 6 7

ZeroToThree: one of 0 1 2 3

Use as few states as possible. States that are legal ending points for escape sequences should be drawn as double circles. To save space, omit the addchar; getChar labels and return actions shown in Sebestas diagrams.
