Welcome back. In this week's Way of the Programmer lesson,
we'll be encouraging a habit of drawing reference diagrams and offer some tips
on how to recognize when to use the accumulation pattern and how to do it well.
The learning objectives: at the end of this lesson,
you should have developed the habit of drawing
a reference diagram to resolve any potential confusions.
And you should be able to recognize when you should use
the accumulation pattern based on
the words that are in the problem statement. See you at the end.
