9) Root is the primary node of the tree. The entire tree is its left sub-tree + right sub-tree + itself.
Root is beginning node of the tree. FOr parsing the tree we start from the root and recursively parse the whole tree.
10) If there is no right subtree or left subtree for a node then it is called leaf node. The general definition is when there are no more children for a given node. The node is classified as external node or leaf node. If a node has atleast one child then it is internal node.
