Problem type

aurpine used to be a pixel painter. However, times have changed. Technology has advanced. These days, it's all about ASCII. Foreign to the new style, he has become depressed. Cheer him up by writing a program featuring the primitive tools he knows from pixel painting. Each operation will be given to you on a single line.

The features and operations are:

c n change the colour used to the given ASCII character n. The letter c will strictly be followed by a single space, followed by the character. The colour could be a space.
r x y w h draw a rectangle starting at $(x, y)$ ~(x, y)~ $(0 \le x, y)$ ~(0 \le x, y)~ with a width (columns) and height (rows) of $w$ ~w~ and $h$ ~h~ respectively $(1 \le w, h)$ ~(1 \le w, h)~.
f x y w h draw a filled rectangle starting at $(x, y)$ ~(x, y)~ $(0 \le x, y)$ ~(0 \le x, y)~ with a width (columns) and height (rows) of $w$ ~w~ and $h$ ~h~ respectively $(1 \le w, h)$ ~(1 \le w, h)~.
h y a b draw a horizontal line on row $y$ ~y~ $(0 \le y)$ ~(0 \le y)~ from column $a$ ~a~ to $b$ ~b~ (inclusive) $(0 \le a \le b)$ ~(0 \le a \le b)~.
v x a b draw a vertical line on column $x$ ~x~ $(0 \le x)$ ~(0 \le x)~ from row $a$ ~a~ to $b$ ~b~ (inclusive) $(0 \le a \le b)$ ~(0 \le a \le b)~.
d x y draw a dot (pixel) at $(x, y)$ ~(x, y)~ $(0 \le x, y)$ ~(0 \le x, y)~.
s save the picture (print the art and close your program).

The default (starting) colour is a period .. The grid initiates with a width and height of 0. It expands so that any edited character/pixel is included in the rectangular area. Note that the point $(0,0)$ ~(0,0)~ is not necessarily always drawn. The background (where nothing has been drawn) defaults to a space character . When printing, pad and trail spaces so that the output consists of $R$ ~R~ rows with $C$ ~C~ characters on each line where $R$ ~R~ and $C$ ~C~ are respectively the rows and columns expanded to. Characters get overwritten when drawn.

Input Specification

$1 \le C, R \le 100$ ~1 \le C, R \le 100~

The farthest pixel ever drawn is at $(99, 99)$ ~(99, 99)~.

There will be at most 100 commands. Input will always end with s on a single line. The finished artwork will never be empty.

Output Specification

A grid of $C$ ~C~ by $R$ ~R~ characters – the resulting artwork created by aurpine.

Note: Output must match exactly.

Explanation for Sample Output 1

First, the 5 by 3 rectangle is drawn with the default colour.

.....
.   .
.....

Then the colour is changed to -. And a horizontal line is drawn.

.....
.   .
.---.

The colour is changed once again and a vertical line is drawn.

The colour is changed to + and a dot is drawn to yield the final drawing.

If a line has trailing spaces at the end, should we output it or go directly to the next line?

Output.

When printing, pad spaces so that output consists of $R$ ~R~ rows with $C$ ~C~ characters on each line

Is length horizontal and width vertical?

Yes. Changed to $w$ ~w~ (width) and $h$ ~h~ (height) for easier comprehension. Shouldn't affect the input.
