Given the root node of a binary search tree (BST) and a value. You need to find the node in the BST that the node's value equals the given value. Return the subtree rooted with that node. If such node doesn't exist, you should return NULL. For example, Given the tree: 4 / \ ...
different values, faster search like binary search for different values is desired, For this purpose, indexes are created on tables. These indexes need extra space on disk, but they allow faster search according to different frequently searched values. 22.What are clustered and non-clustered Indexes?

(N * logN) for any comparative sorting algorithm. This problem also involved counting, which led me to BIT. It worked, as expected. The overall time complexity is actually O(N * log ^ 2 N) instead of O(N * logN), due to the binary search in a BIT. Using a BIT here is because...
