Text messaging is a popular means of communication. Many abbreviations are in common use but are not appropriate for formal communication. Suppose the abbreviations are stored, one to a line, in a text file named abbreviations.txt. For example, the file might contain these three lines:

lol
:)
Iirc
4
u
ttfn

Write a program that will read a message from another text file and surround each occurrence of an abbreviation with <> brackets. Write the marked message to a new text file.

For example, the message to be scanned is

How are u today? Iirc, this is your first free day. Hope you are having fun! :)

the new text file should contain

How are <u> today? <Iirc>, this is your first free day. Hope you are having fun! <:)>
