When he explains the algorithm he begins with all "heads" and counting 2 by 2. The python code begins all "tails" counting 1 by 1. This ends up with the same result obviously because the first iteration sets the list into all "heads". In addition, he switches up to n=qty of coins in the explanation and in the code he goes up to n=qty-1. Since he ends up getting a "tail" in the last position this doesnt screw up the final result where only "heads" are selected.

Hi daniel, thanks for pointing this out! There is a slight difference, indeed, hopefully other students will be able to follow along, as well. Best, Elitsa

The implementation and the explanation of the algorithm are somewhat different
