TC = O(N*constant) INTUITION = When a path is consider from root to any leaf node, count of occurences of nodes should be odd and shouldn't be more than 1. For eg 2->3->3, count of 2=1 and 3=2, so there exists only a single element whose count is odd, therefore, it is a palindrome. recycled adirondack furniture
