Let's try it with recursion:
S0=1
S1=1
S2=2
S3=5
S4=16
Sn=sumk=0..n-1S(k)S(n-1-k)

How many different binary trees and binary?
Infinite (and binary).
How many binary trees are possible with 5 node?
1..15 (not allowing empty trees).
How do you count all structurally different possible Binary Trees?
please tell me answer of this question. Suppose you are building an N node binary search tree with the values 1...N. how many structurally different binary trees is there that store those values? write a recursive function that, gives the number of distinct values, computes the number of structurally unique binary search trees that store those values. For example, countTrees(4) should return 14, since there are 14 structurally unique binary search trees that store 1,2,3 and 4. The base case us easy, and the recursion is short but dense. your code should not construct any actual trees; it's just a counting problem.

How many different trees are possible with 10 nodes?
1014 it is. no of different trees possible with n nodes is (2^n)-n thanx
How many types of binary tree?
A binary tree is type of tree with finite number of elements and is divided into three main parts. the first part is called root of the tree and itself binary tree which exists towards left and right of the tree. There are a no. of binary trees and these are as follows : 1) rooted binary tree 2) full binary tree 3) perfect binary tree 4) complete binary tree 5) balanced binary tree 6) rooted complete binary tree

How many distinct layers of trees in the tropical rain forest?
There is three layers .The ground with shrubbery and maybe dead trees, the second layer is the canopy and the final layer is the emergence.
