The Society for the Prevention of Profanity on the Internet has observed a growing number of chat lines on the World-Wide Web.
A chat line allows a Web user to type lines of text which are transmitted to all other users. The Society is concerned about
the number of four-letter words being transmitted by these chat lines and has proposed the mandatory use of software to remove
all four-letter words from every transmission. Your job is to write the software to do this removal.
