WebTime complexity is O(N log N), same as quick sort. Space complexity is O(N). This is not as efficient as a Fischer Yates shuffle but, in my opinion, the code is significantly shorter and more functional. If you have a large array you should certainly use Fischer Yates. If you have a small array with a few hundred items, you might do this. WebJun 27, 2024 · Fisher-Yates得到的排列就很靠谱了。 它的流程是这样的:从数组的开头开始一位一位往后移,在到达第i位时,随机一个i到n-1的数字k,交换a[i]和a[k]。 由上边的流 …
