Ratiorg got statues of different sizes as a present from CodeMaster for his birthday, each statue having an non-negative integer size. Note: The actual value for a mine is stored as -1, whereas the values stored for display, denote the mine as 'M'. The second candidate can win if all the remaining candidates vote for him (3 + 3 = 6 > 5). So it definitely passed that test. RSA Algorithm: Theory and Implementation in Python.
