The new semester starts and Polivic's girlfriend has bought a
bookshelf but
since she has got so many books and things are in a mess. Of course,
Polivic
is always willing to help.
He wants to illustrate what the bookshelf will look like. As photoshop
never
touches his mind, ASCII is the solution.
Input
There are multiple tests. Each case starts with two integers W and L:
W (width of the bookshelf)
L (levels of the bookshelf)
The following L lines describe each level in the form:
Hi (height of this level) Ni (number of books in this level), followed
by 2Ni
integers for height and width of each book.
A case with W = 0 signals the end of input and this case shall not be
processed.
Output
Print each bookshelf followed with a blank line.
Notice that:
1) The top and bottom of the bookself is of one unit height, and two
unit
wider than the rest levels.
2) On each level the books are arranged from the left-most in the
order of
input.
3) The input is always legal.
Sample Input
20 2
5 2 2 1 4 2
