4. Time & Space Complexity Analysis: 4.1 Time Complexity: 4.1.1 Lists as parameters In each recursive call, the index() function is used to find the index of the root value in the inorder traversal list. This function has a time complexity of O(n) in the worst case, where n is the...
In this article, we covered about Binary tree InOrder traversal and its implementation. We have done traversal using two approaches: Iterative and Recursive. We also discussed about time and space complexity for the traversal. Java Binary tree tutorial Binary tree in java Binary tree preorder trav...
The time complexity of Level Order traversal is o(n) where n is number of nodes in binary tree. This is because each node is visited exactly once during level order traversal. The space complexity of Level Order traversal is o(w) where w is maximum width in binary tree. This is because...

However, traditional mathematical methods struggle with the high complexity and non-linearity of the objective function and constraints when determining parameter values. Hence, this paper employs the particle swarm optimization algorithm and traversal algorithm to obtain the novel model for parameters. The...
Morris Traversal: This algorithm takes O(n) time complexity and O(1) space complexity to complete inorder traversal and preorder traversal. It reconstruct the tree during traversal and recover it after finished traversal. Detailed explanation:Morris Inorder Tree Traversal ...
