Project: Palindrome Search
A [[palindrome]] is a word or phrase that is spelled the same when it is reversed. Write a program that searches a dictionary of English words to find ones that are palindromes and at least four characters in length. Pass the name of the dictionary file to search (one word per line) on the command line.
See Webster's Second International for a file that contains US English words (235k words from 1934 edition) or the open source file [[English Words]] on GitHub (466k words).
