You are required to write two versions: a simple version, where execution efficiency is not taken
into account, and the optimized version where efficiency, in addition to correctness, is a major
concern. Task 1 is about the simple version. Task 2 is about the optimized version. Task 3 is a
report.
With the exceptions of ArrayList and LinkedList, you are not permitted to use any of the
classes in the Java Collections Framework, e.g. TreeMap, HashMap.
