简单加密

输入两个数

#include<iostream>
#include<string>
using namespace std;

int main()
{ 
 
  

	int data, key;

	cin >> data;
	cin >> key;
	
	string  str = to_string(data);
	int size = str.size();
	string res(size,-1);//必需要初始化，不然下面会报错

	for (int i = 0; i < size; i++)
	{ 
 
  
		res[i]=str[(i+key)%size];
	}

	int result = stoi(res);

	cout << result;

	return 0;

};
