Exactly, the number of 3's should be less than 3, not 9. There is a mistake in the editorial, I think. Also, it will not be 3 * 3 rather 3 * 6 because each 3 increases the sum a total of 6.

Thank you so much for the editorial. I solved the problem. By the way, I sometimes struggles a lot to understand the recursion process. If you give any suggestions, I will be incredibly grateful.

We wish you will. Good Luck!
