1. Draw a state diagram to recognize floating-point constants in C, which are defined by the following EBNF rules: [ ] [ ] cfract-constant> [ ] * exponent> e [ ] digit-sequence> [ ] I E1 + I- digit> I digit> 0111213141516171819 f | | | F I L Use as few states as possible. States that are legal ending points for floating-point constants should be drawn as double circles (see the states labeled "id" and "int" in Figure 4.1 of Sebesta). To save space, omit the "addchar getchar" labels and "return" actions shown in Sebesta's diagrams. You may use the name Digit to represent the characters listed in the
