31 Ιουλ 2024 · In this tutorial, we are going to solve or make a solution to the Hackerrank Tree: Top View problem. so here we have given a pointer to the head or root node of a binary tree and we need to print the top view of the binary tree.
Problem Statement : Given a pointer to the root of a binary tree, print the top view of the binary tree. The tree as seen from the top the nodes, is called the top view of the tree.

Given a pointer to the root of a binary tree, print the top view of the binary tree. The tree as seen from the top the nodes, is called the top view of the tree. For example : 1 \ 2 \ 5 / \ 3 6 \ 4 Top View : Complete the function and print the resulting values on a single line separated by space.
The tree as seen from the top the nodes, is called the top view of the tree. For example : 1 \ 2 \ 5 / \ 3 6 \ 4. Top View : 1-> 2 -> 5 -> 6. Complete the function TOPVIEW and print the resulting values on a single line separated by space. Input Format. You are given a function, void topView(node * root) {} Constraints. 1<= Nodes in the tree ...
Actually there's no need to keep track of depth or to use another function, here's an example solution: void topView ( Node * root ) { queue < pair < int , Node *>> q ; q . push ( make_pair ( 0 , root )); map < int , Node *> ans ; for ( auto i = q . front (); ! q . empty (); q . pop (), i = q . front ()){ if ( ! i . second ) continue ; ans ...
