那个不行的话发地址我给你下载。
⑵ 通讯录拼音搜索模糊匹配的算法问题
我用java写了个简单的，你可以多测试下：
publicstaticvoidmain(String[]args){
String[]name={"wang","hai","bao"};
String[]tests={"whb","WaHB","wangHB","HB","wh","whbo","whba"};
for(Stringstring:tests){
System.out.println(string+":"+match(name,string));
}
}
publicstaticbooleanmatch(String[]source,Stringinput){
if(source==null||source.length==0||input==null||input.length()==0){
returnfalse;
}
Stringtemp;
//统一转小写
input=input.toLowerCase();
for(inti=0;i<source.length;i++){
temp=source[i].toLowerCase();
if(temp==null||temp.length()==0){
returnfalse;
}
//最后一步特殊处理
if(i==source.length-1){
if(temp.startsWith(input)){
returntrue;
}
}
//输入的字符完全匹配到
if(input.startsWith(temp)){
//匹配到后生成新的字符串
input=input.substring(0,input.indexOf(temp));
//System.out.println("temp:"+temp+" 匹配到后input："+input);
}
//首字母匹配到
elseif(temp.startsWith(input.substring(0,1))){
input=input.substring(1);
//System.out.println("temp:"+temp+" 匹配到后input："+input);
}else{
returnfalse;
}
//表示匹配结束
if(input.length()==0){
returntrue;
}
}
returnfalse;
}

⑷ C++简单通讯录的设计与实现
去网络文库找经典C程序吧，然后自己改改！
⑸ 抖音的算法思维是什么
1、抖音推荐算法第一要看发作品受欢迎的程度，简单说就是：点赞数评论数转发数完播率，也就 是说，新视频的完播率高，互动率高，这个视频才有机会持续加持流量；第二看 抖音账号权重大小，抖音账户权重基本算法=在抖音爸爸这里的位置。抖音推荐上热门的基础逻辑：基础流量、推荐叠加、时间效应。
2、抖音搜索算法搜索流量的秘密，用户搜索——浏览视频——涨粉变现， 而且抖音搜索算法还有以下三个特点：精准、持续性强、被动享受。 通过关键词字面意思，我们就可以知道，用户搜 索这个关键词的目的是什么。如果你是与关键词相关的内容，那搜索这个关键词的用户对你来说就是非常精准的潜在客户。如果你的视频标题和视频内容吸引了他的注意，点击你的视频，并且被你的视频所吸引， 进而就会进入你的账号主页，然后找到你的联系方式，最后成交。因此你要知道如何去布局抖音关键词，你布局的 关键词越多，精准性越高，关键词排名越好，你的流量也就越大。

（1）∵由题意知甲获得实习机会需要笔试和面试得分之和至少为25分，包括两种情况：一是笔试和面试得分之和为25分；二是笔试和面试得分之和为30分，这两种情况是互斥的笔试和面试得分之和为25分的概率为p1＝C23×(34)2×14×C33×(12)3+C33×(34)3×C23×(12)2×12＝27128，笔试和面试得分之和为30分的概率为p1＝C33×(34)3×C33×(12)3＝27512，∴甲获得实习机会的概率为p＝p1+p2＝27128+27512＝135512．（2）ξ的取值为0，5，10，15，20，25，30．p(ξ＝0)＝C33×(14)3＝164，p(ξ＝5)＝C13×34×(14)2＝964，p(ξ＝10)＝C23×(34)2×14×C03×(12)3＝27512，p(ξ＝15)＝C23×(34)2×14×C13×(12)3+C33×(34)3×C03×(12)3＝108512，p(ξ＝20)＝C23×(34)2×14×C23×(12)3+C33×(34)3×C13×(12)3＝162512，由（1）知p(ξ＝25)＝108512，p(ξ＝30)＝27512．∴Eξ＝0×164+5×964+10×27512+15×108512+20×162512+25×108512+30×27512＝112564
