Another popular interview question/assessment is to invert a binary tree. This is where all the left and right children of all non-leaf nodes are interchanged. Think of it as a mirror of the input tree. This can be visually understood as follows, where 4 is the root node and its subsequent children are inverted. Reverse the array and store elements back in the tree. Method 2 (Using Two Traversals): Another method is to do two inorder traversals. The following are the steps to be followed. Traverse the given tree in inorder fashion and store all odd level nodes in an auxiliary array.

Binary Search Tree. A Binary Search Tree is a binary tree with a search property where elements in the left sub-tree are less than the root and elements in the right sub-tree are greater than the root. Ex.

• Algorithm for Reverse a Path in BST using Queue. Reversing a path from the root to the node is same as reversing the elements of the nodes on the path from the root to the node. For example, if the path from the root to the node is 5 -> 10 -> 15 -> 20, then reversing the path is the same as reversing the data. So the reversed path is 20 ->15.
