字符串模拟“编程开发”

思路：判断的时候直接将所有kkk…h变成h就行了
C++代码：

#include 
using namespace std;

map mp;
int main()
{
    int n;
    cin >> n;
    string s,t;
    for(int i = 0;i < n;i++)
    {
        cin >> s;
        t = "";
        for(int j = 0;j < s.size();j++)
            if(s[j] == 'u')
                t.push_back('o'),t.push_back('o');
            else if(s[j] == 'h')
            {
                while(t.back() == 'k')
                    t.pop_back();
                t.push_back('h');
            }
            else
                t.push_back(s[j]);
        mp[t]++;
    }
    cout << mp.size() << "\n";
    return 0;
}

Python直接用replace：

n = int(input())
ans = []
for i in range(0,n):
    s = input()
    s = s.replace("u","oo")
    while s.count("kh") != 0:
        s = s.replace("kh","h")
    if not s in ans:
        ans.append(s)
print (len(ans))
