+Implementation
+==============
+This is a class of problems where the problem-solving strategy is trivial or
+given as part of the problem statement. The challenge for the programmers is to
+implement the strategy correctly for all cases. Different ways of modeling the
+problem or different code structures may affect the complexity: a well-designed
+structure not only makes the code more reable but also makes the solution much
+shorter (takes less time to type).
