Draw a finite state machine (fsm) for a string representing a single time of day. your fsm should accept times such as 12: 36 pm, 1: 59 am, 4: 00 pm, 2: 45 am. note that there are no leading zeros. also, "am" and "pm" are lowercase and hace no periods. a terminal error state is not neccesary. to make the task easier, you can make up any grouping you want. for example, you may wish to leat represent any digit, let < 1> represnt the digit 1, let < 012> represent and digit 0-2, and let represent a space. time statements are formatted in many ways but we want your fsm to only accept the above time format -- not military time or any other time format.

This question involves a class named textfile that represents a text file. public class textfile { private string filename; private string filename; private arraylist words; // constructors not shown // postcondition: returns the number of bytes in this file public int filesize() { } // precondition: 0 < = index < words.size() // postcondition: removes numwords words from the words arraylist beginning at // index. public void deletewords(int index, int numwords) { } // precondition: 0 < = index < = words.size() // postcondition: adds elements from newwords array to words arraylist beginning // at index. pub lic voidaddwords(int index, string[] newwords) { } // other methods not shown } complete the filesize() method. the filesize() is computed in bytes. in a text file, each character in each word counts as one byte. in addition, there is a space in between each word in the words arraylist, and each of those spaces also counts as one byte. for example, suppose the words arraylist stores the following words: { mary had a little lamb; its fleece was white as snow. } the filesize() method would compute 4 + 3 + 1 + 6 + 5 + 4 + 6 + 3 + 5 + 2 + 5 as the sum of the lengths of each string in the arraylist. the value returned would be this sum plus 10, because there would also be 10 spaces in between the 11 words. complete the filesize() method below: // postcondition: returns the number of bytes in this file public int filesize() { }
