In Vertical Order Traversal, if two nodes share the same horizontal distance, what determines their order?

VERTICAL ORDER TRAVERSALYou are given root of a binary tree, your task is to print the nodes in order obtained via vertical traversal of the tree.The vertical order traversal of a binary tree is a list of top-to-bottom orderings for each column index starting from the leftmost column and ending on the rightmost column. There may be multiple nodes in the same row and same column. In such a case, sort these nodes by their values.For each node at position (row, col), its left and right children will be at positions (row + 1, col - 1) and (row + 1, col + 1) respectively. The root of the tree is at (0, 0).Input format :The first line contains the number of test cases.For each test case: You are given a pointer to the root of the binary tree.Output format :Print the nodes in order obtained via vertical traversal of the tree. Refer the same Input/Output provided.Sample test cases :Input 1 :11 2 3Output 1 :2 1 3 Note :The program will be evaluated only after the “Submit Code” is clicked.Extra spaces and new line characters in the program output will result in the failure of the test case.

uses a queue data structure for traversal, not a stack. This ensures that nodes arevisited in the order of their distance from the starting node.
