[WIP] add dominoes

[seanreed1111]

working on dominoes

[tute]

Is this the same as returning dominoes_list.length == 0?

Note: Ruby defines the zero? method on numbers:

% irb
irb(main):001:0> 1.zero?
=> false
irb(main):002:0> 0.zero?
=> true

Ah this is true, but I do not believe and of the solutions beyond the base cases are dependent on length. I just wanted to get the base cases out of the way.

My suspicion is that I need to frame finding the generic solution as a graph, and then figure out how to traverse the graph to see if at least one solution exists..

Yes, you are correct of course. Will do that as I get into refactoring..

Is this the same as https://ruby-doc.org/core-2.3.1/Object.html#method-i-clone? If so, can we use the Ruby method?

[seanreed1111]

Yes, I believe I can use clone method. Need to investigate differences between using clone and dup in this context when I have a minute.

Are you still working on this?

[seanreed1111]

hey, sorry, I got busy with work. I still want to do it, and I believe I know how. though if someone else wants it immediately I will defer.

[Insti]

@seanreed1111 still busy with work? It would be good to be able to merge this in.

[seanreed1111]

Ugh. Ok, final countdown!
Either I will finish this by Wednesday at 11:59pm or you can close it down and let someone else do it. It's been sitting too long.

Is that OK?
