Censor
frog is now a editor to censor so-called sensitive words (敏感词).
She has a long text p. Her job is relatively simple -- just to find the first occurence of sensitive word w and remove it.
frog repeats over and over again. Help her do the tedious work.
Input
The input consists of multiple tests. For each test:
The first line contains 1 string w. The second line contains 1 string p.
(1≤length of w,p≤5⋅106, w,p consists of only lowercase letter)
Output
For each test, write 1 string which denotes the censored text.
Sample Input
abc
aaabcbc
b
bbb
abc
abSample Output
a
ab
上面是题目，大致要求：
W串是可疑串，P是输入串，在P中将出现的W串删除，然后输出P串；
下面是我写的代码：
#include<iostream>
#include
using namespace std;
int main()
{
string s1,s2; //s1用于做可疑串，s2用于做输入串
while(cin>>s1)
{
cin>>s2;
while(-1!=s2.find(s1)) //s2字符串中存在可疑串
{
s2.erase(s2.find(s1),s1.size());
}
cout<<s2<<endl;
}
return 0;
}
求大神编写一个C++程序，运行时间很低的程序，谢谢各位大牛了；
