What is the primary goal of Dynamic Programming?

  1. To find the shortest path between two points.

  2. To solve optimization problems.

  3. To find the maximum value of a function.

  4. To find the minimum value of a function.


Correct Option: B
Explanation:

Dynamic Programming aims to solve optimization problems by breaking them down into smaller subproblems, solving each subproblem optimally, and combining the solutions to obtain the optimal solution to the original problem.

Which of the following is a key principle of Dynamic Programming?

  1. Recursion

  2. Memoization

  3. Divide and Conquer

  4. Greedy Algorithms


Correct Option: B
Explanation:

Memoization is a key principle of Dynamic Programming. It involves storing the solutions to subproblems so that they can be reused later, avoiding redundant calculations and improving efficiency.

What is the time complexity of the Fibonacci sequence using Dynamic Programming?

  1. O(2^n)

  2. O(n)

  3. O(log n)

  4. O(n^2)


Correct Option: B
Explanation:

Using Dynamic Programming, the Fibonacci sequence can be solved in O(n) time complexity by storing the solutions to subproblems in a table and reusing them as needed.

Which of the following problems can be solved using Dynamic Programming?

  1. Traveling Salesman Problem

  2. Knapsack Problem

  3. Longest Common Subsequence

  4. All of the above


Correct Option: D
Explanation:

Dynamic Programming can be used to solve a variety of problems, including the Traveling Salesman Problem, Knapsack Problem, and Longest Common Subsequence.

What is the essence of Bellman's Principle in Dynamic Programming?

  1. Optimal substructure

  2. Divide and Conquer
