Ask the user to enter a sequence of numbers. Let's call this sequence A. Thereafter ask the user to enter a number B.

A number is considered good if it is a positive power of B. So B, B*B, B*B*B, B*B*B*B*B are examples of good numbers. Output all the good numbers in the list A. You may assume list A contains no duplicate numbers.

Sample Output 1:

Please enter A: 9 31 20

Please enter B: 3

The good numbers present are 39

The order in which you output which are present does not matter. You need only consider positive powers of B. So B, B*B, B*B*B and so on. Sample Output 2:

Please enter A: 931 20 11 2 1024 8

Please enter B: 2

The good numbers present are 2 8 1024
