@Hex:
It’s a good idea to consider that some cards could remain undealt depending on the number of players, but then a different solution is called for. Since in most card games all the players get equal number of cards in the starting deck, she should put aside C modulo P cards, and then deal from herself clockwise….

Still, if each player is to end up with the same cards that they would have gotten had there been no interruption, Alice must start by dealing FROM THE BOTTOM OF THE DECK to herself, and proceeding clockwise.

If she resumed dealing from the top of the deck, a true card-player(as Obiwan observed) would declare a misdeal.

Ah, bit of a trick question that. No mention of players so I think my answer still stands that she could be on her own :-)

If “unclockwise” means “anticlockwise”, when she comes back
she should start dealing cards in clockwise, dealing first card to herself.

That is the only possible way without any misunderstanding.

As most of you have already correctly pointed out, Alice should deal to herself and continue clockwise. Congrats to those who got it!
Soon I will post the second puzzle in the series, which will be more demanding. Anyway this one was supposed to be a warm-up ;-)

Are we to assume she plans to deal the entire deck? If so, she need only deal to herself and continue in the opposite direction – clockwise (which is how most people deal anyway).

Deal the rest of the cards starting at the other end and going in the opposite direction.

this one has me stumped a bit. I want to say that she should deal the cards in reverse order because thats the only thing i can think of.

Alice could have started with the player she would have finished with and deal backwards if she was dealing out the entire deck. If she was only dealing a hand of 5 or 7 or whatever, I know of no way without everyone counting their cards.

Knowing the number of cards in the deck (C, normally = 52) and the number of persons (P), Alice can calculate who will get the last card. She will continue dealing from that person clockwise.
Let’s consider she is person 0 and the person right after her (counterclockwise) is person 1 … until person P-1. She should continue dealing from person C modulo P clockwise.

She only had the time to deal one card to some of the players. The players she forgot don’t have a card yet.

Start by dealing clockwise one position on from first start

Start dealing clockwise from the person who is one space clockwise of the person you originally started dealing at. All this will change is who gets any “extra” cards (which are extra if the numPeople % 52 != 0).

Maybe the deck of card was pointing towards the last person that was dealed,cool.
