We know that a binary tree is a rooted tree in which each node has no more than two children. We can extend this definition to an n-ary tree. If a tree is rooted in which each node has no more than n children, it is called an n-ary tree. In other words, n ary trees are tree data structures with up to n children nodes for each node present in the tree.
