In a slightly different vein, here are some smaller brainteasers for you to try!

• Create an algorithm which divides any two numbers of different bases together.
  Does your algorithm work with negative numbers?
  How about negative bases?
• How would you find a cycle in a linked list?
  Can you do it iteratively?
• Multiply a number by 7 without using the multiplication operator.
  Can it be done without addition?
