/*
对于C语言有分大小写的子串查找函数strstr，对于这题用strstr解决不了，因为它的子串匹配根据样例输出可以看出是不分大小写的，所以我就（借助不分大小写的比较函数strncasecmp和指针）自己写了个不分大小写的子串匹配函数，我叫它Strstr。

AC_code:

#include <stdio.h>
#include <string.h>
#include <algorithm>
using namespace std;
char *Strstr(char *a,const char *b)
{
    int len_b = strlen(b);
    while(*a)
    {
        if(strncasecmp(a,b,len_b)==0)
        {
            return a;
        }
        a++;
    }
    return NULL;
}
int main()
{
    char a[205];
    while(gets(a))
    {
        int len = strlen(a);
        char *p = a;
        const char *q ="marshTomp",*f = "fjxmlhx";
        while(Strstr(p,q))
        {
            char *start = Strstr(p,q);
            *start = '\0';
            *(start+1) = '\0';
            strncpy(start+2,f,7);
            p++;
        }
        for(int i = 0; i < len; i++)
        {
            if(a[i]!='\0')
                printf("%c",a[i]);
        }
