WebDec 1, 2024 · The Fisher–Yates shuffle is an algorithm for generating a random permutation of a finite sequence—in plain terms, the algorithm shuffles the sequence. The algorithm effectively puts all the elements into a hat; it continually determines the next element by randomly drawing an element from the hat until no elements remain. The … Web我將接受Aidan Cully的回答,因為事實證明我正在重新發現Fisher-Yates算法,並揭示了這個問題的核心。 當然,通過預先做一些研究,我可以節省自己的時間和精力也就不足為奇了。 但另一方面,這是一個有趣的愛好項目。
WebSecond position with second position gives one of: A B C -> A B C. B A C -> B A C. C B A -> C B A. and finally second position with third position gives one of: A B C -> A C B. B A C -> B C A.
