Detailed explanation-1: -In a binary tree, all nodes have degree 0, 1, or 2. A node of degree zero is called a terminal node or leaf node. A non-leaf node is often called a branch node.
Detailed explanation-2: -A terminal node is a node like a leaf at the edge of the tree; no other nodes exist beyond it (hence “terminal"). A non-terminal node is any node that exists in the graph between other nodes.
Detailed explanation-3: -A binary tree is a tree structure where each node has at most two children. Some data is stored at each node. Nodes with children are called interior nodes while nodes without children are called leaf nodes .
Detailed explanation-4: -A node can have any number of children. A leaf is a node with no children. An internal node is a non-leaf node Siblings are nodes with the same parent.
Detailed explanation-5: -For finding the leaf nodes, we will have to traverse the tree and check every node. If both the left and right child of a node is equal to NULL, it is a leaf node. After the traversal of the tree is done, we will sort the array containing the leaf nodes in ascending order.
