Given deck of cards A and deck of cards B, which deck would you rather choose from if you need to choose two cards of the same color on consecutive draws? Deck A is a normal 52 card deck, Deck B is a 26 card deck with 50% black and 50% red. What if we add deck C, which is a 26 card deck that comes from a random subset of deck A?

given a series of real numbers, what's the optimal point in real line that minimize the distance between all these numbers? follow up: what's the best algorithm to calculate the median of a sequence of numbers? follow up2: design a algorithm able to update the median of sequence as there are new numbers coming in.
