Re: [QUIZ] Circle Drawing (#166)

## Circle Drawing (#166)

This week we're going to keep it simple... very simple.

Given a radius, draw an ASCII circle.

For example:

ruby circle.rb 7

Should produce a circle of radius 7:

#####
## ##
# #
# #
# #
# #
# #
# #
# #
# #
# #
# #
# #
## ##
#####


Note that most fonts do not have a square aspect ratio, which is why the
above output may look like an oval, despite my calculations for a circle. It
is acceptable if your code produces similar output.


However, _for extra credit_ you may support an additional argument that
specifies the aspect ratio (height divided by width).

ruby circle.rb 7 1.4

This should draw a circle of radius 7 with aspect ratio of 1.4. If done
correctly, your output will actually look like a circle (assuming 1.4 is an
accurate measure of the actual aspect ratio).





A bit of ruby art :-)

I don't know if my benchmark is done properly.. I do it quickly and just
for fun :-) Please give me feedback..

Benchmark details:

num_of_runs = 100
radius = 7
ratio = 2.0

This benchmark has been executed on a MacBook 2,16Ghz with 2Gb of RAM
running Linux Ubuntu 7.10.
