(1) implement the following functions of a Queue using an integer array: • queue_init(): Make the queue empty empty(): return true if the queue is empty. Return otherwise • enqueue(val): add the item val to the queue • dequeue(): remove the item least recently added to the queue front(): return the item least recently added to the queue, but do not remove it. (ii) the program reads in integer values as input: for a positive integer input value greater than 0, the program will insert the value into the queue, i.e. enqueue • for any negative integer input value, the program will return the least recently added value from the queue if it is non-empty, i.e. front for the input value 0, the program will remove the least recently added

What exactly does it mean when someone says they are going to assault you with a poison package, and what does it imply? Please provide two examples of this kind of violent attack.

I'd be very grateful if you could elaborate on the goals of the authentication process. Think about the benefits and drawbacks of the various authentication methods now in use.

4) Question 2 asked you to compute the number of possible passwords with various numbers of characters.  However, it seems more likely that most people will choose actual words for their password.  According to the website wordfinder.yourdictionary.com, the English language has approximately 23,000 six-letter words.  a) Assume that a password must be at least 8 characters long and include at least 1 digit and at least 1 special character (again, assume there are 30 of these that are allowed). If people form their password by taking an English word of exactly 6 letters (assume that this password is not case-sensitive) and then adding (in either order) a digit and a special character (e.g flames#1), how many passwords would be possible?  (Hint: Find the number of passwords with 6 letters followed by a digit and a special character, then exchange the order of the last two characters.)  b) How does your answer change if we assume passwords are case-sensitive and the password must…
