Given a sorted array of size N and an integer K find the position at which K is present in the array using binary search.

. Hey guys Ill be solving the Mirror Tree problem on Geeks For GeeksThis problem is also called as Invert the Binary Tree problem in LeetcodeThis problem is. Following is the code to invert a Binary Tree recursively. Root 4271369 Output.

It is known that in 1 second all nodes connected to a. The tree is 10 10 mirror 20 30 30 20 40 60 60 40 The inroder traversal of mirror is 30 10 60 20 40. Given the root of a binary tree invert the tree and return its root.

Given the root of a binary tree invert the tree and return its root. Root 213 Output. 1 3 2 Output.

Root 4271369 Output. Odd Even Level Difference. Nodes at level 2 are reversed.

Given a binary tree invert it and return the new value. Ancestors in Binary Tree. To invert a binary tree switch the left subtree and the right subtree and invert them both.

Maximum sum leaf to root path. 1 2 3 Explanation. Given a complete binary tree reverse the nodes present at alternate levels.

Return None Swapping the children temp rootleft. 30 10 60 20 40 Explanation. Find the minimum time required to burn the complete binary tree if the target is set on fire.

Left View of Binary Tree. 1 2 3. Given a binary tree and a node called target.

The code is almost similar to the level. 10 20 30 40 60 Output. We can easily convert the above recursive solution into an iterative one using a queue or stack to store tree nodes.

Minimize the Heights II. You may invert it in-place. Minimum distance between two given nodes.
