Answer / baskerdearer
number of possible tree = (2 power n) - n.
for example:
A tree contain three node.
so n=3.
possible tree = 8 - 3 = 5.

Answer / vikram_tp
you all are going wrong...
the formula which u have given is only working when n=2 or 3..
bt when n=4 the ans should be 14 not 12
when n=5 ans is 42 and not what comes by the formula...
so there isnt any formula for this..u have to count then by generating the trees by urself...

Answer / sudip
If there are 3 nodes A,B and C. In which A is root and B and
C are it's left and right child...
Then if we want to count the no. of tree..then..
A A A A-alone, B -alone and
/ \ / \ C-alone and the last
B C B C one is null tree.
I think there will be 7 subtrees if we null is subtree then,..
no. of tree = 2^n - 1.
