Problem A - SMS Encoder
-----------------------

People who use SMS (Short Message Service) to send text messages on
their mobile telephones and other devices often abbreviate phrases to
squeeze more meaning into a message that is required to be short.

You must write a programme that takes an input string and creates an
SMS version of it by doing some simple substitutions.  First you
should replace some words by their abbreviations.  Below is a list of
the word substitutions you should make.

later -> l8r
at -> @
that -> th@
to -> 2
for -> 4
one -> 1
see -> c
you -> u
be -> b
not -> !
love -> luv

Note that you should *not* replace portions of words using the above rules.
For example, do not change "into" to "in2".

After making the word substitutions, you should replace double s by $, 
double t by #.  Thus, "kiss" becomes "ki$", "pretty" becomes "pre#y".

Input Format
------------

The first line of the input file will contain the number of words in
the passage to be translated.  All input will be presented in
lower-case letters, and there will be no punctuation.  Words will be
separated by spaces or carriage returns.

Output Format
-------------

You should output the encoded message with the same spacing as the
original message.

Sample Input (for Valentine's Day)
------------
