   Online Assessment90 min

   The Online Assessment (OA) had 4 coding questions on a private platform. The difficulty ranged from Easy to Hard, covering topics like arrays, strings, and trees. Each question had multiple test cases and supported partial scoring, so even a partially correct solution could earn some points.

   • Easy: Check if a string is a palindrome after removing one character
   • Medium: Subarray with a given XOR
   • Medium: Clone a linked list with random pointers
   • Hard: Maximum score of a path in a grid with dynamic constraints
