1.最容易想到的估计就是利用String类的toCharArray(),再倒序输出数组的方法了: package himi.hebao05; public class TestDemo02 { public static void main(String[] args) { int i = 0; String text = "hebao I love you!"; String result = " "; char[] charArray = text.toChar
curl请求的url中含有空格时(例如rul的参数是sql查询语句,url=www.tets.com/query.php?sql=select * from t1),curl_easy_perform()将不会得到正确的结果. 需要处理一下空格,用%20替换掉每一个空格,即将select * from t1换成select%20*%20from%20t1
一:根据标点符号分行,上图,代码很简单 二:代码 using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace Lines { public partial class Fr
/** 取出字符串中重复字数最多的字符 */ var words = 'sdfghjkfastgbyhnvdstyaujskgfdfhlaa'; //创建字符串 var word, //单个字符 length; //该字符的长度 //定义输出对象 var max = { wordName : '', //重复次数最多的字符 wordLength : 0 //重复的次数 }; //递归方法,传入字符串 (function(words) { if (!words) return; //如果字符串已经

这里用到了三个函数: #判断是否为数字:str.isdigit()#是否为字母:str.isalpha()#是否为空格:str.isspace() def tongji(str): alpha = 0 number = 0 space =0 qt = 0 for i in range(len(str)): #或者for i in str: if str[i].isalpha(): #接上一句改为:i.isalpha() alpha += 1 elif str[i].isdigit(): numb
