This exercise is similar to the exercises for the past few weeks, but read these instructions carefully in order to obtain grade credit for what you submit.
Functional programming is probably new and unfamiliar to most students in the class.
Find, or write, an example functional program that does some straightforward task. The program may be in any of the languages discussed in chapter 14 of the textbook. Be sure to cite completely and accurately the source of your example, including links and authorship of web pages. In order to demonstrate that you have devoted some effort to understanding what your example program does, include, in your html submission, a narrative explanation of what your sample program does, and how it does it. Your description should be written in English by yourself, expressed in your own words.
