Vertical order traversal of tree is a method to traverse a binary tree in a vertical order.

• Perform a level order traversal of the tree and keep track of the horizontal distance of each node from the root

• Store nodes at each horizontal distance in the map and then print the nodes in each vertical level

Other methods of sorting include bubble sort, selection sort, and insertion sort.

• Bubble sort: repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order.

• Selection sort: repeatedly finds the minimum element from the unsorted part of the array and swaps it with the first unsorted element.

• Insertion sort: builds the final sorted array one item at a time by inserting each element into its correct position.
