字符串替换 hihoCoder1082 然而沼跃鱼早就看穿了一切

一直因为C++里面没有现成的替换函数而烦恼，只怪自己太懒懒的写

借这题写好这个函数，，以后直接用就好了

#include<map>
#include<set>
#include<cmath>
#include<stack>
#include<queue>
#include<cstdio>
#include<string>
#include<vector>
#include<cstring>
#include<iostream>
#include<algorithm>
#include<functional>
using namespace std;

const int MX = 1e3 + 5;

string Replace(string s, string a, string b, bool Match = false) {
    string tmp = s;
    if(!Match) {
        transform(tmp.begin(), tmp.end(), tmp.begin(), ::tolower);
        transform(a.begin(), a.end(), a.begin(), ::tolower);
    }

    int pos;
    while(true) {
        if((pos = tmp.find(a)) != -1) {
            tmp.replace(pos, a.length(), b);
            s.replace(pos, a.length(), b);
        } else break;
    }
    return s;
}

char S[MX], a[MX] = "marshtomp", b[MX] = "fjxmlhx";

int main() {
    while(gets(S)) {
        printf("%s\n", Replace(string(S), string(a), string(b)).c_str());
    }
    return 0;
}
