c++标题太短写点废话

解题思路:

注意事项:

参考代码:

#include<iostream>

#include<unordered_map>

#include<string>

using namespace std;

unordered_map<char, int>p;

bool jud(int k)

{

if (k <= 1)return 0;

if (k ==2)return 1;

for (int j = 2; j < k; j++)

if (k % j == 0)return 0;

return 1;

}

int main()

{

string a;

int maxn = 0, minn = 99;

cin >> a;

for(int i=0;i<a.size();i++)

    p[a[i]]++;

for (auto it : p)

{

if (it.second > maxn)maxn = it.second;

if (it.second < minn)minn = it.second;

}

int c = maxn - minn;

if (jud(c) == 1) {

cout << "Lucky Word" << endl;

cout << c;

}

else {

cout << "No Answer" << endl;

cout << 0;

}

return 0;

}
