在之前的一篇文章.NET性能系列文章一:.NET7的性能改进中我们聊到Linq中的Min()和Max()方法.NET7比.NET6有高达45倍的性能提升,当时Benchmark代码和结果如下所示: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 [Params(1000)]publicint Length{get;set;}privateint[]arr;[GlobalSetup]publicvoidGlobalSetu...
分别是： max(A)：返回一个行向量，向量的第i个元素是矩阵A的第i列上的最大值。
returnMath.min.apply(Math, array); }; The premise behind this technique is simple (and obvious once you see it): Just find any built-in JavaScript function that takes unlimited arguments - it'll now be just as easy to adapt it for Array-wide use. By using JavaScript's .apply() metho...

Fast JavaScript Max/Min via:john resighttp://ejohn.org/blog/fast-javascript-maxmin/I've been saving this technique for a while now - it's simple, but it's good. What's the fastest way to find the largest, or smallest, number in an array?There's a bunch of implementations ...
The JavaScript Math.min() method finds the minimum value among the specified values and returns it. In this tutorial, you will learn about the min() method with the help of examples.

min(): 获取表中最小值 arr = [10,1,2,5,100,77]print(max(arr))print(min(arr)) xxx.index(): 获取列表中第一次找到某个元素的索引(下标值) 普通写法: 列表.index('列表中的某个元素') 获取列表中第一次找到某个元素的索引(下标值)
