Implement the FSM for figure 6-4 (pg 220). This FSM validates a certain type of string, the description is given above it (Character String Example). Use some of the author's procedures to show the input. Output a string that states whether the input was valid. Include comments that show your test cases. The code for validating a signed integer is listed in section 6.6.2. This can be used as a template for the string validation FSM.
