Interview Questions

GalacticInterviewer - "Approach 1: Use sorting and return the kth largest element from the sorted list. Time complexity: O(nlogn) Approach 2: Use max heap and then select the kth largest element. time complexity: O(n+logn) Approach 3: Quickselect. Time complexity O(n) I explained my interviewer the 3 approaches. He told me to solve in a naive manner. Used Approach 1 had some time left so coded approach 3 also The average time complexity of Quickselect is O(n), making it very efficient for its purpose. However, in"See full answer

Anonymous Mollusk - "My weakness was stage fright and talking in front of a large audience.

An D. - "First find the node that we need to delete. After it's found, think about ways to keep the tree BST after deleting the node. a. If there's no left or right subtree, we found the leaf. Delete this node without any further traversing. b. If it's not a leaf node, what node we can use from the subtree that can replace the delete node and still maintain the BST property? We can either replace the delete node with the minimum from the right subtree (if right exists) or we can replace the delete"See full answer

Sohum S. - "I would assume that this is similar to an intervals question. Meeting Rooms II (https://www.lintcode.com/problem/919/?fromId=203&_from=collection) on Leetcode seems like the closest comparison, it's a premium question so I linked Lintcode. I'm assuming that we also need to just return the minimum number of cars used. You need to sort for the most optimal solution, so you're constrained by an O(nlogn) time complexity. So any sorting solution could work (using a heap, sorting the array input arra"See full answer

Adarsh S. - "Hey, Thanks for the question - it’s an interesting real-life existing problem wherein a few of my friends and colleagues who have tried to work and travel have faced these issues at their respective airBnBs. Cool so this is the rough backbone structure that we can follow and ofcourse we can add meat later on to it and pivot if required. So here it goes: First would like to lay out the broader mission of Airbnb + WHY this is needed as to why we are doing this and then some clarific"See full answer
