• 题目大意:把字符串中的 “WUB”去掉

#include <vector>
#include <string>
#include <iostream>
using namespace std;
int main(){
        string str,s;
        cin>>str;
        int m = str.length();
        vector<string> v;
        for(int i = 0 ; i < m;++i){
                if(i + 2 < m && str[i] == ‘W‘ && str[i + 1] == ‘U‘ && str[i + 2] == ‘B‘){
                        i += 2;
                        if(s != ""){
                                v.emplace_back(s);
                                s = "";
                        }
                }else  s += str[i];
        }
        if(s != ""){
                v.emplace_back(s);
                s = "";
        }
        m = v.size();
        for(int i = 0 ;i < m - 1 ;++i){
                 cout<<v[i]<<‘ ‘;
        }
        cout<< v[m - 1]  <<‘\n‘;
        return 0;
}

#include <cstdio>
#include<cstring>
using namespace std;
char str[200 + 10];
int main(){
        gets(str);
        int m = strlen(str),cur = 0,flg = 0;
        for(int i = 0; i < m ;++i){
                if(i + 2 < m && str[i] == ‘W‘ && str[i + 1] == ‘U‘ && str[i + 2] == ‘B‘){
                        i += 2;
                        if(flg) str[cur++] = ‘ ‘;
                }else {
                        str[cur++] = str[i];
                        flg = 1;
                }
        }
        str[cur] = ‘\0‘;
        printf("%s\n",str);
        return 0;
}
