Evaluation

  • Correctness of code
  • Efficiency of algorithms (time and space complexity)
  • Clarity and organization of code
  • Problem-solving approach

Sample questions

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

    ArrayDynamic ProgrammingKadane's Algorithm
  • Implement a function to check if a binary tree is a Binary Search Tree (BST).
