The following BNF rules are a simplified version of the ones that are used to unsigned numbers in the Alogl60 language. Design a state diagram to recognize these literals. un signed number ::= decimal number I exponential part l decimal number ::- unsigned integer l | unsigned integer digit> decimal fraction ::- unsigned integer exponential part> ::= E integer integer : unsigned integer | + ::= 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 Use as few states as possible. States that are legal ending points for unsigned numbers should be drawn as double circles. Use the abbreviation Digit to represent any digit. To save space, omit the "addchar; getChar" labels and "return" actions shown in Sebesta's diagram
