In this problem you will write a simple guessing game for the user to guess a random number between 0 and 511 (up to 10 points extra credit if you can make it between 1-400 instead without bias).
Your program should flow as follows: Asks the user to enter a user name. Makes a call to "syscall $random" and sets the result as the initial LFSR state.
Calls state = LFSR(state) nine times to generate a random number between 0 and 255 using value B from each subsequent state.
For up to nine guesses Ask the user to guess a number. If the user guesses correctly, congratulate the user and end the program.
Tell the user whether the guess was too high or too low. Tell the user that all nine guesses were used, and the random number.
