//!@Alan
//!
//! Exercise 5.14:
//! Write a program to read strings from standard input looking for duplicated
//! words. The program should find places in the input where one word is followed immediately
//! by itself. Keep track of the largest number of times a single repetition occurs and which
//! word is repeated. Print the maximum number of duplicates, or else print a message saying
//! that no word was repeated. For example, if the input is
//  how now now now brown cow cow
//! the output should indicate that the word now occurred three times.
//!
