This problem really made my day, joke of the year
\nclass Solution {\n    int r,c;\n    Random rand = new Random();\n    public Solution(int n_rows, int n_cols) {\n        r = n_rows;\n        c = n_cols;\n    
```\nclass Solution {\n    int r,c;\n    Random rand = new Random();\n    public Solution(int n_rows, int n_cols) {\n        r = n_rows;\n        c = n_cols;\n    }\n    \n    public int[] flip() {\n        int i = rand.nextInt(r);\n        int j = rand.nextInt(c);\n        return new int[]{i,j};\n    }\n    \n    public void reset() {\n        return;\n    }\n}\n```
