[Zerojudge]a009: 解碼器

利用ASCII碼找出Sample Input和Sample Output相差的k值，
將輸入的每個字都以此k值做加減即可得解。

P.S. k值為7

[C++](6ms, 730KB)

	#include<iostream>
	using namespace std;
	int main()
	{
	const int k = 7;
	string s;
	while( getline( cin, s ) )
	{
	for( int i = 0 ; i < s.length() ; i++ )
	s[i] -= 7;
	cout << s << endl;
	}
	return 0;
	}
