Ch. 1: Carefully describe your approaches and solution(s), or attempts at solution(s), to any one of the nine stories in the first chapter. The story can be one that we discussed in class or not, as you like. You may include ideas you got from other people in class, as long as you fully acknowledge that. The emphasis on this first assignment is your description of your approaches.
