package main

func main() {
    //1.统计字符串长度
    //str:="sdffsfdsf";
    //fmt.Println(len(str));
//2.字符串变量同时出现中文的
    //name:="你好水电费第三方是dsfs";
    //slice:=[]rune(name);//使用rune切片转换为字节切片

//3.字符串转化为整数
    //num:="12321";
    //nums,_:=strconv.Atoi(num);
    //fmt.Println(nums);
//4.整数转化为字符串返回值一个数字
    //num:=12312;
    //info:=strconv.Itoa(num);
    //fmt.Println(info);
//5.字符串转化为字节切片因为是字节所以字节切片里面是整数
    //str:="sdfdsfsd";
    //str_slice := []byte(str);
    //for _,val:=range str_slice{
    //    fmt.Println(val);
    //}
//6.字节切片转换为字符串
    //nums:=string([]byte{97,98,99});
    //fmt.Println(nums);
//7.查找子传是否在父字符串里面返回true|false
    //str_Children :="aa";
    //str_Parent:="aabbcc";
    //bol:=strings.Contains(str_Parent,str_Children);
//8.统计一个子字符串在父字符串里面出现的次数
    //str:="e";
    //strparent:="adfdsesdfsee";
    //nums:=strings.Count(strparent,str);
    //fmt.Println(nums);
//9.比较字符串不区分大小写
    //str1:="ABC";
    //str:="abc";
    //bol:= strings.EqualFold(str1,str);
    //fmt.Println(bol);
//10.返回子字符串第一次出现的位置index
    //str:="abcefefd";
    //target:="fd";
    //num:=strings.Index(str,target);
    //fmt.Println(num);

//11.字符串替换replace -1标识全部替换
    //str:="abcedfdsfssfdooo";
    //target:="ooo";
    //replace:="<<<<";
    //new_str:=strings.Replace(str,target,replace,-1);
    //fmt.Println(new_str);

//12.字符串切割成字节切片
    //str:="sdfjslkdfjdslkfjdslkfds";
    //arr:=strings.Split(str,"");
    //fmt.Println(arr);

//13.大小写转换
    //str:="sdfsdfdss";
    //target:=strings.ToUpper(str);//转换为大写
    //fmt.Println(target);
    //str:="DJFLKSJFLKDS";
    //target:=strings.ToLower(str);//转为小写
    //fmt.Println(target);
//14.去除左右两边空格
    //str:="  ssdfdsfssf ";
    //target_str:=strings.TrimSpace(str);
    //fmt.Println(target_str);
    //new_str:=" sdjfkls jfslkjsd fdsf ds !!";//去除制定空格
    //info:=strings.Trim(new_str,"!");
    //fmt.Println(info);
