5. (I1 points) Consider a language L of variable names for a restricted Java programming for which variable names must satisfy all of the following conditions A variable name only uses Roman letters ta, b. . 0,1,2,..9. No underscore or dollar sign is allowed. A variable name must start with a Roman letter: a, b, . The length of a variable name must be no greater than 8. language, ,.. 2) or Aabie numerals A, B . , z, .. Z For this language, provide: a) a regular expression, and b) an e-NFA nt: In the interest of time, there is no need to label the states in your solution. You may define sets of symbols:l-a,b... zA.B.z. 22 0,1,2,.,9), and use 1 and 22 to define your regular expression. For the NFA one option is for you to simply derive it from your regular expression of Hi part (a)
