The Inorder sequence of the tree is “bbaaabb” which is a palindromic string.
The Inorder sequence of the tree is “bbdaabb” which is not a palindromic string.
To solve the problem, refer to the following steps:
- Convert the given Binary Tree to a Doubly Linked List.
- This, reduces the problem to Check if a doubly linked list of characters is palindrome or not.
Below is the implementation of above approach:
Time Complexity: O(N)
Auxiliary Space: O(1)
