Kapil P. - "Sounds like both the features requests address different problems, although it should be clarified in my opinion. I'd try to dig deep into why the customers are raising the requests to uncover the pain points. Questions like the following would help: "How are you currently solving it?" "What does it mean for you in terms of Cost or productivity?" (based on the context of the product) "Have you searched for an alternative?" Descriptive answers for the above questions should tell us if the"See full answer

Javed S. - "One good reason for using the doubly linked list is that to remove an accessed item in the list from its existing position say in the middle of the list and move it to the head, you need to update the previous node's next pointer and the next node's previous pointer. A singly linked list only has next pointers, so removing from the middle would require traversing from the head to find the previous node which requires O(n) time. A doubly linked list allows O(1) removal from any position because w"See full answer

Karan K. - "2 Approaches: 1) The more intuitive approach is doing a multi-source BFS from all cats and storing the distance of closest cats. Then do a dfs/bfs from rat to bread. Time Complexity: O(mn + 4^L) where L is path length, worst case L could be mn Space Complexity: O(m*n) 2) The first approach should be fine for interviews. But if they ask to optimize it further, you can use Binary Search. Problems like "Finding max of min distance" or "Finding min of max" could be usually solved by BS. "See full answer

Umang S. - "Just a bit of context on what could be a risk in Product or Software Development. We talk about the Scope, Quality, and Time Triangle. IMHO the only variables that can matter and can pose risk are these. Try to form an answer where you used the Effort, Value, Risk framework to quantify the risk. The answer can be similar to short term sacrifices for long term gains, as you do take in mind the risk the short term sacrifices pose.
