From desc.: "2D array size tuple (width, height)"

It should be (but I also have problems with getting correct values):

(3,3)

[0,1,2]

[3,4,5]

[6,7,8]

==========

(2,4)

[0,1]

[2,3]

[4,5]

[6,7]

should be fixed

replaced the tab with 4 spaces

Changed a part of the description - if there are more places that need formatting, specify below.

That's ok too, sometimes, leaving it for later is for the best. I'm pretty sure a facepalm will happen when you solve it ;) .

No, nothing that fancy, no. You know you can forfeit and see the solutions if you give up, don't you?

added triangle type in the description
too late to switch between dots/spaces

I was sitting here contemplating life because i just couldnt understand the logic of a 7kyu..nonetheless thanks for the clarification

description updated

Done.

if you haven't heard about that story with the reward from the king already, you won't be able to solve this.

I did solve it and didn't know about it beforehand.

Calculate the amount of grains on a given field

Shouldn't this be on a given square?

Changed. Thank you!

Well, description is simply awefull... I don't know how I can help you without spoiling too much, but actually you may find out some bitwise operator better than operate on binary strings...
