顺时针打印数组，美丽版

今天看到一段代码，顺时针打印数组。写得太美了，简洁明了，几乎不用任何注释。

转过来，原来是java版的，我改成了C++版。

    void PrintMatrixClockWise()
    {
        int m = 5;
        int n = 4;
        int val[4][5] = 
        {    
            {1,    2,    3,    4,    5 },
            {6,    7,    8,    9,    1 },
            {11,   12,   13,   14,   15},
            {16,   17,   18,   19,   20}
        };

        int colMin = 0;
        int colMax = m;
        int rowMin = 0;
        int rowMax = n;

        while(colMin < colMax && rowMin < rowMax)
        {
            for(int i = colMin; i < colMax; i++)
                cout << (val[rowMin][i]) << " ";
            cout << endl;
            rowMin++;

            for(int i = rowMin; i < rowMax; i++)
                cout << (val[i][colMax-1]) << " ";
            cout << endl;
            colMax--;

            for(int i = colMax-1; i >= colMin; i--)
                cout << (val[rowMax-1][i]) << " ";
            cout << endl;
            rowMax--;

            for(int i = rowMax-1; i >= rowMin; i--)
                cout << (val[i][colMin]) << " ";
            cout << endl;
            colMin++;
        }
    }
