Evaluation

  • Problem-solving approach
  • Algorithmic thinking
  • Data structure knowledge
  • Coding proficiency
  • Understanding of time and space complexity

Sample questions

  • Given a binary tree, find the lowest common ancestor of two given nodes in the tree.

    Data StructuresAlgorithmsTrees
  • Implement a function to find the k-th largest element in an unsorted array.
