Saurabh S. - "Basic Approach As BST inorder traversal will result in a sequence of increasing order. Store that order in a vector and get the k-1 index to get the Kth smallest element, similarly access the N-K+1 th element will be the Kth largest element Time Complexity: O(n) Space Complexity O(n) Space Optimized Approach For Kth smallest , start inorder traversal, and keep a counter, decrement the counter when you access the node element. When the counter turns 0 that elementwill be the Kth smal"See full answer

Exponent - "Although it's not totally obvious, this is a Strategy Question, which asks you to justify business decisions at a high level. First, let's provide a few reasons why Display Ads are bad, and then propose an alternative solution. > There are a few reasons why display ads are a bad idea.

Prachi N. - "My the current KPIs focus on three areas: 1) the number of designs finalized and signed off by the business. 2) the completion of development for those designs, and 3)the quality and quantity of data loaded. To achieve these, I communicate requirements early and provide all necessary information to the business for accurate design sign-off. I deliver documents that are precise and contain all details the technical team needs for development. I also verify system configuration before data loadin"See full answer

Sri V. - "Switching from a linear kernel to RBF / Gaussian kernel is likely to result in overfitting the model. It is a move that adds complexity to the mix, and if the data doesn't need that sort of complexity, it would result in overfitting. On the other hand, all the other three approaches would only try too reduce complexity in the process, thereby doesn't contribute to overfitting the model."See full answer
