Given a Tree where every node contains variable number of children, convert the tree to its mirror. Below diagram shows an example.
We strongly recommend you to minimize your browser and try this yourself first.
Node of tree is represented as a key and a variable sized array of children pointers. The idea is similar to mirror of Binary Tree. For every node, we first recur for all of its children and then reverse array of children pointers. We can also do these steps in other way, i.e., reverse array of children pointers first and then recur for children.
Below is C++ implementation of above idea.
