Coin Flip Conundrum

I watched this video,

Very interesting.

So, I managed to prove it through some scripting.

And I get some result like this,

[code lang=text] Result: Target: [0, 1] average steps = 3.987 Target: [0, 0] average steps = 5.9505 [/code]

P/S: Wrote a robust flip coin script, which can accept the coin tossing sequence with any length. [here]
