用js实现,今天是今年第几周? 基本思路: 1.当前时间 - 今年1月1日0时,拿到时间差(毫秒数) 2.时间差/7天毫秒数,向上取整 var d = new Date('2018-01-01 00:00:00') var timeHold = (new Date()).getTime() - d.getTime() var currWeek = Math.ceil( timeHold/(7*24*3600000) )
如何通过运行程序输出程序源码? 下面是JAVA实现 public class Quine { public static void main(String[] args) { char q = 34; // Quotation mark character String[] l = { // Array of source code "public class Quine", "{", " public static void main(String[]
用快速排序的思想输出数组第k大的元素: #include<iostream> #include<algorithm> using namespace std; //递归实现:返回数组第k大的值.数组下标区间是[begin,end].其中数组假定n个元素,则k的值在区间[1,n]. //能够使用这种方法的前提条件是:n个数不能重复.如果n个数中有重复,那么区间的大小不能保证就是第K大. int findkth(int* arr, int begin, int end, int k)
DescriptionCD You have a long drive by car ahead. You have a tape recorder, but unfortunately your best music is on CDs. You need to have it on tapes so the problem to solve is: you have a tape N minutes long. How to choose tracks from CD to get most
背景:当你输日文汉字的额时候,输出它的读音. 如下图所示 实现的代码如下 Option Explicit ' Replace を まとめて おこなう Private Function ReplaceA(ByVal s As String, ByVal t1 As String, ByVal t2 As String) As String Dim u1() As String: u1 = Split(t1) Dim u2() As String: u2 = Split(t2) Dim i As I
public class TestFileInputStream { public static void main(String [] args) { //读取指定文件中内容,并在控制台输出 FileInputStream fis = null; byte[] b = new byte[1024]; int len = 0; try { fis = new FileInputStream("E:\\javafile\\ja.txt"); while((len = fis.read(b
