Tonight is card game night! You are the dealer and your task is to write a program to deal the cards to the players.
Given an array of card and a number of player, you need to split the array into hand for each player.
Rules
Your program will receive an non-empty array A , as well as a non-zero positive integer n. The array should then be split into n hands, if the length of the string isn't divisible by n any leftover at the end should be distributed as evenly as possible.
- If
nis equals to 1, you will need to return an array of arrayA
If
nis greater than the length ofA, you will need to return every hands and an empty hand. ifn = 4andarray A = [1,2,3], you should return[[1],[2],[3]]or[[1],[2],[3],[]]. You are free to handle the empty hand with empty, undefined or null.The array can contain any type rather than a number.
You should not change order (or direction) of any item from left to right. For example
if n = 2andA= [1,2,3]. Any result rather than[[1,3],[2]]will be invalid.
Test Cases
n A Output
1 [1,2,3,4,5,6] [[1,2,3,4,5,6]]
2 [1,2,3,4,5,6] [[1,3,5],[2,4,6]]
3 [1,2,3,4,5,6] [[1,4],[2,5],[3,6]]
4 [1,2,3,4,5,6] [[1,5],[2,6],[3],[4]]
7 [1,2,3,4,5,6] [[1],[2],[3],[4],[5],[6]] // or [[1],[2],[3],[4],[5],[6],[]]
Demo
def deal(cards, n):
i = 0
players = [[] for _ in range(n)]
for card in cards:
players[i % n].append(card)
i += 1
return players
hands = deal([1,2,3,4,5,6], 2)
for hand in hands:
print(hand)
Try it online!
This is code-golf, so you the shortest bytes of each language will be the winner.

@Shaggy ok I will take it into account for the next time. It is fine on so and rpg but I guess the competitive aspect of codegolf made it a bit unfair to self post directly. Make sense.

Does this handle the
[1,2,3], 4 case correctly? Your code seems to be returning [[1],[2],[3]] rather than [1,2,3]$endgroup$

@JoKing
[1,2,3], 4 should output [[1],[2],[3]]. You are dealing 3 cards to 4 players. I will update the main question.$endgroup$

If this is an answer to a challenge…
…Be sure to follow the challenge specification. However, please refrain from exploiting obvious loopholes. Answers abusing any of the standard loopholes are considered invalid. If you think a specification is unclear or underspecified, comment on the question instead.
…Try to optimize your score. For instance, answers to code-golf challenges should attempt to be as short as possible. You can always include a readable version of the code in addition to the competitive one.
Explanations of your answer make it more interesting to read and are very much encouraged.…Include a short header which indicates the language(s) of your code and its score, as defined by the challenge.
More generally…
…Please make sure to answer the question and provide sufficient detail.
…Avoid asking for help, clarification or responding to other answers (use comments instead).

@aloisdg Great, but now your first bulleted rule is unnecessary and wrong.

you will need to return every hands and an empty hand contradicts the last test case's first result possibility.
