Given a binary tree and two nodes of that binary tree. Find the sum of all nodes with odd values in the path connecting the two given nodes.
For Example: In the above binary tree, sum of all odd nodes in the path between the nodes and will be 5 + 1 + 3 = 9.
Approach : The idea is to first find the path between the two given nodes of the binary tree using the concept as discussed in: Print path between any two nodes.
Once, we have the path between the two given nodes, calculate sum of all the odd valued nodes in that path and print it.
Below is the implementation of the above approach:
Time Complexity : O(n)
Auxiliary Space : O(n)
- Minimum and maximum node that lies in the path connecting two nodes in a Binary Tree
- Find triplet such that number of nodes connecting these triplets is maximum
- Remove all nodes which don't lie in any path with sum>= k
- Check whether the given node is in the path between the nodes U and V
- XOR of path between any two nodes in a Binary Tree
- Print path between any two nodes in a Binary Tree | Set 2
- Print path between any two nodes in a Binary Tree
- Print the path common to the two paths from the root to the two given nodes
- Root to leaf path with maximum distinct nodes
- Sum of nodes on the longest path from root to leaf node
- Queries to check if the path between two nodes in a tree is a palindrome
- Shortest path between two nodes in array like representation of binary tree
- Find the path from root to the given nodes of a tree for multiple queries
- Print path from root to all nodes in a Complete Binary Tree
- Implementing a BST where every node stores the maximum number of nodes in the path till any leaf
