Problem:
 Score : 100 points    Problem Statement  The door of Snuke's laboratory is locked with a security code.  The security code is a 4 -digit number. We say the security code is hard to enter when it contains two consecutive digits that are the same.  You are given the current security code S . If S is hard to enter, print Bad ; otherwise, print Good .      Constraints   S is a 4 -character string consisting of digits.         Input  Input is given from Standard Input in the following format:  S       Output  If S is hard to enter, print Bad ; otherwise, print Good .        Sample Input 1 3776      Sample Output 1 Bad  The second and third digits are the same, so 3776 is hard to enter.       Sample Input 2 8080      Sample Output 2 Good  There are no two consecutive digits that are the same, so 8080 is not hard to enter.       Sample Input 3 1333      Sample Output 3 Bad       Sample Input 4 0024      Sample Output 4 Bad
