Julius Caesar used his way to encrypt text. Each letter is replaced by the following in alphabetical order by K positions in the circle.
You are given a cypher. Your task is to write a program that outputs plain text.

Answer 1

#include <iostream>
using namespace std;

void swap2(unsigned int *a, unsigned int *b)
{
unsigned int c;
c = *a;
*a = *b;
*b = c;
}

int main()
{
unsigned int a, b;
cin >> a >> b;
swap2(&a, &b);
cout << a << " " << b << endl;
return 0;
}
