Programming Challenge 5.14 - Student Line Up

/* Student Line Up - A teacher has asked all her students to line up single
file according to their first name. For example, in one class Amy will be
at the front of the line and Yolanda will be at the end.

This program prompts the user to enter the number of students in the class,
then loops to read that many names. Once all the names have been read it
reports which student would be at the front of the line and which one would
be at the end of the line. It is assumed that no two students have the same
name.

Input Validation: No number less than 1 or greater than 25 for the number of
students are accepted. */
