AOJ Volume 0 Problem 0077 : Run Length

#include <iostream>
using namespace std;

int main()
{
    char ch, n;
    while (cin.get(ch))
    {
        n = '1';
        if (ch == '@')
            cin >> n >> ch;

        for (int i = 0; i < n - '0'; ++i)
            cout << ch;
    }

    return 0;
} 

まともに解きすぎてると思う．
もっと柔らかく思いつきたい．
