Return to the Pyramids

You may recall from 150 having to draw a Pyramid out of bricks. Well, this time I want you to build a pyramid out of stars! They will be symmetrical and look like: 

    *    
   ***   
  *****  
 ******* 
*********
  1. Given a height N, give the loops needed to print a pyramid of that height. You may do this in Java, Python, or even pseudocode

HiLo guessing game

You and your friend (the computer) will play a guessing game. One of you will pick a number between 1 and 1000. The other one will guess numbers and the other will tell them if they guessed correctly or were too high/low.

  1. Describe the logic needed to ensure that a user types in a guess between 1 and 1000

Redaction

  1. Describe how you could accurately determine the number of lines in a text file

You'll also want to think about different ways you might be able to match words on that line. (i.e., do some String matching)
