A level is full if it contains the maximum allowable number of nodes (e.g., in a binary tree level k can have up to 2k nodes). The fill-up level finds many interesting applications, e.g., in the internet IP lookup problem and in the analysis of level compressed tries (LC tries)....
Average of Levels in Binary Tree Given a non-empty binary tree, return the average value of the nodes on each level in the form of an array. Example 1: Input: 3 / \ 9 20 / \ 15 7 Output: [3, 14.5, 11] **Explanation:** The average value of nodes on level 0 is 3, on ...
Given a non-empty binary tree, return the average value of the nodes on each level in the form of an array. Example 1: Input: 3 / \ 9 20 / \ 15 7 Output: [3, 14.5, 11] Explanation: The average value of nodes on level 0 is 3, on level 1 is 14.5, and on level 2 is 11...
In this problem, we are given a binary tree and we have to print all nodes at a level in sorted order of their values. Let’s take an example to understand the concept better, Input − Output − 20 6 15 2 17 32 78 To solve this problem, we need to print a sorted order of...
Discover the various levels of pointers in C and C++. Learn how many levels you can use and their significance in programming.
