    Coding Round60 min

    Given an array, you can increase or decrease up to K elements by 1 to maximize the sum of any subarray. Find the maximum achievable sum.

    Given a binary tree and two players, Player A starts from the root and can only move down (to children). Player B starts from any node and can only move up (to parent). Both players take turns moving. Task - Maximize the score for Player A (the one starting at the root). Each node has a value, and the player moving into the node adds that value to their score. How do you find the best possible final score for Player A?
