Evaluation

  • Correctness of the solution
  • Efficiency of the solution (time and space complexity)
  • Code quality, readability, and maintainability
  • Ability to handle edge cases and constraints
  • Problem-solving approach and communication

Sample questions

  • Given an array of integers, find the contiguous subarray with the largest sum.

    ArrayDynamic Programming
  • Implement a function to reverse a linked list.

    Linked List
  • Find the k-th smallest element in a binary search tree.

    TreeBinary Search TreeRecursion
