On the first sight I thought there is a problem which requires 9-Dimensional Segment Trees. LOL :D

First of all, your link to the problem isnt correct. I think you meant this.The task in simple english is :

Given n ( no. of distinct nodes) and h (the minimum height) , you need to print the number of binary search trees possible. For sample case 1, the no. of distinct nodes is 3 and the minimum height required is 2. So the following 5 BST are possible.

I hope the problem is clear now.
