Question: What is tree traversal?
Reference answer: Tree traversal is a process to visit all the nodes of a tree. Because, all nodes are connected via edges (links) we always start from the root (head) node. There are three ways which we use to traverse a tree − (1) In-order Traversal (2) Pre-order Traversal (3) Post-order Traversal

Score: 1.0

Student answer: AVL Tree is a type of tree. Its node has a value called balance factor. Balance factor is the mod of number of nodes on left of a node - number of nodes on right side.\nThis balance factor cannot be greater than 1 at any instant. To maintain the balance factor the AVL tree has rotations which are done when there is an imbalance on any node. This helps as there can be certain cases in Binary search tree where the depth of the tree is too large and the data is stored inefficiently but rotations in AVL tree allow us to maintain the height by doing rotations hence ensuring a efficient storage of data in tree.

Question: What is an AVL Tree?
Reference answer: AVL trees are height balancing binary search tree. AVL tree checks the height of left and right sub-trees and assures that the difference is not more than 1. This difference is called Balance Factor. BalanceFactor = height(left-sutree) − height(right-sutree)

Student answer: AVL tree is height balanced BST in which each node is associated with a balance factor which is calculated by subtracting the height of its right sub-tree from that of its left sub-tree. it is said to be balanced if balance factor of each node is in between -1 to 1  else the tree will be unbalanced and need to be balanced.\n\n

Student answer: Quick sort works by making partitions in any data structure, say it is an array, and then the array is partitioned in half. It works on divide and conquer approach so it keeps on making multiple partitions until it is efficient enough such that we can then sort the partitioned array in the most efficient manner and then re-join it such that the whole array is sorted towards the end. It takes a time complexity of O(nlogn).
