Question 1 –Easy level –

  • Simple Question that can be solved by basic applications of Aptitude, Algorithm and Data Structures.

Question 2 – Medium Level – Usually a question based on Greedy Algorithm

  • A greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. Types of greedy problems are-:
    • Pure Greedy Algorithms
    • Orthogonal Greedy Algorithms
    • Relaxed Greedy Algorithms

Question 3 – Hard level – Usually a question based on Dynamic Programming

  • DP is an algorithmic technique for solving an optimisation problem by breaking it down into simpler subproblems and utilising the fact that the optimal solution to the overall problem depends upon the optimal solution to its subproblems.
  • Principles of Dynamic Programming-:
    • Breaking the problem down into subproblems and calculating their values. Next time, upon encountering the same subproblem, the value can be reused instead of recalculation
    • Avoid repeated work by remembering partial results, a common approach for performance enhancements.
