FAQ

列表随机排序工具可以用于哪些场景？

可用于多种场景：抽奖活动随机抽取中奖者、课堂随机点名、团队随机分组、比赛出场顺序抽签、问卷答案随机排列、姓名或物品的随机排序等。所有处理在浏览器本地完成，数据不会被上传。

随机排序的算法可靠吗？

本工具使用Fisher-Yates（也称为Knuth）洗牌算法，是业界公认的公平随机排序算法。每个排列出现的概率都是均等的，保证了真正的随机性。每次点击随机按钮都会产生不同的结果。

最多可以输入多少个项目？

理论上没有数量限制，但建议每次不超过500个项目以保证浏览器性能。对于大量项目，工具内部的Fisher-Yates算法仍能高效处理（时间复杂度为O(n)）。您可以随时清空列表重新输入。
