Given a binary tree. The task is to find the value of the deepest node in the given binary tree.
Input: Root of below tree 1 / \ 2 3 / \ / \ 4 5 6 7 \ 8 Output: 8 Input: Root of below tree 1 / \ 2 3 / 6 Output: 6
Approach: We have already discussed the two different ways to find the deepest node in a binary tree in this post. Here, we will find the deepest node in the tree using a queue data structure. We will first push the root into the queue and then we will push it’s child nodes after removing parent node from the queue. We will continue this process until the queue empty. The last node in the queue is the deepest node of the binary tree.
Below is the implementation of the above approach :
Time Complexity: O(N)
- Find the Deepest Node in a Binary Tree
- Depth of the deepest odd level node in Binary Tree
- Deepest left leaf node in a binary tree
- Deepest right leaf node in a binary tree | Iterative approach
- Deepest left leaf node in a binary tree | iterative approach
- Find depth of the deepest odd level leaf node
- Find maximum and minimum element in binary tree without using recursion or stack or queue
- Find the parent of a node in the given binary tree
- Find mirror of a given node in Binary tree
- Find n-th node in Preorder traversal of a Binary Tree
- Find the color of given node in an infinite binary tree
- Find distance from root to given node in a binary tree
- Find the node with minimum value in a Binary Search Tree
- Find the node with maximum value in a Binary Search Tree
- Find n-th node in Postorder traversal of a Binary Tree
