Reduce takes the first two elements of a list and
replaces them with the result of a function, then
repeats until the list is single valued.
So to get the longest string just compare two
strings and return the longest one. The final list
contains the longest string in the original list.
Take a look at the Functional Programming page of
my tutor for more on reduce() and its friends.
