The Data for Display in Detail
------------------------------
Based on what we have done before, we can readily foresee that it should
not be too hard to write a function that CDRs down the lengths’ list,
looks at each element, determines which length range it is in, and
increments a counter for that range.
However, before beginning to write such a function, we should
consider the advantages of sorting the lengths’ list first, so the
numbers are ordered from smallest to largest. First, sorting will make
it easier to count the numbers in each range, since two adjacent numbers
will either be in the same length range or in adjacent ranges. Second,
by inspecting a sorted list, we can discover the highest and lowest
number, and thereby determine the largest and smallest length range that
we will need.
