Considering it to be a strictly binary tree, if the number of leaves is n then the number of nodes is (2n-1).br /Hence, is the above given question, the number of nodes will be {(2*20)-1} = 39

In Binary tree if there are N leaf nodes then the number of Nodes having two children will be N-1. So in this case answer will be 20-1, means 19.
