What is the time complexity of binary tree?
Therefore, searching in binary search tree has worst case complexity of O(n). In general, time complexity is O(h) where h is height of BST.
What is the time complexity of level order traversal of a binary tree with n nodes?
Time complexity = O(n), where n is the total number of nodes. Level order traversal require space proportional to the max width of the tree (w) which is equal ot the maximum number of nodes at a given level. Space Complexity = O(w)(Think!)
What is the difference between complete binary tree and full binary tree?
Full v.s. Complete Binary Trees. A full binary tree (sometimes proper binary tree or 2-tree) is a tree in which every node other than the leaves has two children. A complete binary tree is a binary tree in which every level, except possibly the last, is completely filled, and all nodes are as far left as possible.
What is the best case complexity of binary search tree?
Best Case- The binary search tree is a balanced binary search tree. Height of the binary search tree becomes log(n). So, Time complexity of BST Operations = O(logn).
What is minimum depth in binary tree?
The minimum depth of a binary tree is the number of nodes from the root node to the nearest leaf node. The minimum depth of this tree is 3; it is comprised of nodes 1, 2, and 4.
How do you print nodes in a binary tree?
Given a binary tree, print its nodes level by level, i.e., print all nodes of level 1 first, followed by nodes of level 2 and so on… Print nodes for any level from left to right.
How to traverse a binary tree level by level?
Given a binary tree, we are supposed to traverse the tree using the level order traversal. Level order traversal is just another word for the Breadth First Traversal i.e. traverse the tree level-by-level.
How to print the level Order of a tree?
There are basically two functions in this method. One is to print all nodes at a given level (printGivenLevel), and other is to print level order traversal of the tree (printLevelorder). printLevelorder makes use of printGivenLevel to print nodes at all levels one by one starting from root.
How to print level order traversal line by line?
Given a binary tree, print level order traversal in a way that nodes of all levels are printed in separate lines. Recommended: Please solve it on “ PRACTICE ” first, before moving on to the solution.
