[jugalparulekar]

Great explanation. Keep up the good work!

[rajez.s]

Really an awesome explanation. But one thing i noticed is, that the example we have: ""we are comparing each digit in the numbers."" So, in that case, we should not chosen 10 instead, it should be 1, 0 - Apart from this everything looks really great and intuition is really clear.
