Hints on Exercise 1.5 and 1.6 Always, always, always be thinking about REUSING rather than RESTATING an existing algorithm. So, if you've already been given an algorithm for finding the smallest number in a list (as we did in class), don't spend time describing that algorithm when you want to find the second smallest number in the list. Assume you can always find the smallest, and that you can remove any number you want from the list. Then your second-smallest algorithm reduces to three very short sentences. Likewise, once you've described an algorithm, you should refer to it instead of repeating it, when using it in another algorithm.
