五名水手在岛上遭遇海难,并在白天收集了一大堆椰子。

那天晚上,第一个水手醒来并决定早点拿走他的第一份,所以试图将一堆椰子平分成五堆,但发现剩下一个椰子,所以他把它扔到一只猴子然后隐藏“他的”五个同样大小的椰子堆中的一个,并将其他四个桩推到一起,再次形成一堆可见的椰子并上床睡觉。

长话短说,每个水手轮流在夜间起床,并执行将椰子堆分成五个的相同动作,发现剩下一个椰子并将剩下的椰子留给猴子。

在早上(在夜间五个水手的暗中和分开行动之后),剩下的椰子被分成五个相等的堆,每个水手,然后发现一堆椰子在水手之间平分没有余数。 (早上猴子没什么。)

任务:

  Create a function that returns the the minimum possible size of the initial pile of coconuts collected during the day for N sailors. 

注意:

  Of course the tale is told in a world where the collection of any amount of coconuts in a day and multiple divisions of the pile, etc can occur in time fitting the story line, so as not to affect the mathematics.
