Answer / shweta
for no. of different binary tree---
for n nodes the formula is 2^n-n in this formula value of
nodes are not considered, only the way nodes can be present
in a tree so for 3 nodes there can be 5 ways, for each way
no. of possibilty of values is 3! so answer comes out to be
5*6=30
1 1 1 1 1
A A A A A
2 3 2 2 2 2
A A A A
3 3 3 3
for binary search tree answer is 3
