Dynamic clockwise rotating board

Guys I need some help. I need to write a code for a dynamic clockwise rotating board. The user inputs the number of rows, and lines, and the code needs to count the numbers, where number 1 is in the bottom right corner, and counts the numbers clockwise to the center. It needs to look like this:
5- 6- 7

4 9- 8
