Xavier's Xmas Trees
-------------------

Xavier, who featured in last week's problem, likes to send Christmas cards to
celebrities he has never met, but is too cheap to buy cards.  Instead, he prints 
his own, cuts them out and mails them.  He likes to send different size cards
to different people.  Thus, really major celebrities (according to Xavier's 
reckoning), like Shirley Bassey, get big cards, while minor celebrities like
Lady Gaga get smaller cards.  Xavier has decided on Xmas trees as the theme
for this year's cards.  Write a programme to help Xavier print his cards.
