b、不一样的地方在于,每次循环的步长,通过减半的方式来实现 c、说明:基本原理和插入排序类似,不一样的地方在于。通过间隔多个数据来进行插入排序。 1publicstaticvoidmain(String[] args) {2int[] arr = {7, 5, 3, 2, 4};34for(inti = arr.length / 2; i > 0; i /= 2) {5//i层循环控制步长...

find() 方法非常适合用于需要基于某个条件从数组中检索单个元素的场景。 3)findIndex() 是 JavaScript 数组的一个内置方法,它与 find() 方法类似,但 findIndex() 返回的是数组中符合条件的第一个元素的索引,而不是元素本身。 语法如下:array.findIndex(callback(element, index, array), thisArg); callback:...
用法:array.find(function(currentValue, [index], [arr]),[thisValue]) vararr = [1,2,3,4,5];vararr1 = arr.find(function(value){returnvalue >= 3; }); console.log(arr1);//3 6、findIndex() 方法:返回符合条件(函数内判断)的数组第一个元素位置。
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and ...
