Matching braces in a string

I heard recently about an interview problem involving matching braces in a string. Checking to see if all the braces in a string are paired up in the proper order. Seemed like an interesting, and short, challenge.

Examples of strings with proper brace matching: "()", "(){}[]", "([{}])"

Examples of strings without proper brace matching: "(", "[]]", "([)]"

Then I’d check the comments to see if anybody re-posted it on imgur, most of the time nobody had.

Langton’s Ant


A little while ago I came across the topic of Cellular Automata. I was fascinated about the idea that complex (and even Turing-complete) behavior can come from a system that follows a few simple rules.

One of the more simple types of cellular automaton is Langton’s ant. This type seemed like a good choice to start with. I’ve been wanting to get into Python for a while now so I figured this would be a good project to get my feet wet.
