## How do I become an expert in competitive programming?

How to become a master in competitive programming?

1. Get thorough understanding. First of all study all the concepts of the programming language deeply.
2. Follow a hierarchical approach. Try to start coding using simpler problems.
3. Implementation in real life.
4. Truncate the code.
5. Be a fighter.
7. Be updated.

What is the difference between Divide and conquer and dynamic programming?

Divide and Conquer works by dividing the problem into sub-problems, conquer each sub-problem recursively and combine these solutions. Dynamic Programming is a technique for solving problems with overlapping subproblems.

### When to use divide and conquer or dynamic programming?

Divide and Conquer should be used when same subproblems are not evaluated many times. Otherwise Dynamic Programming or Memoization should be used. For example, Binary Search is a Divide and Conquer algorithm, we never evaluate the same subproblems again.

What is competitive programming and how does it work?

Competitive programming is solving coding problems using algorithm and data structure. The participants need to write code under various restrictions like memory limits, execution time, limit of coding, space, etc. The winner is declared base on some problems solved and time spent on writing successful programming…

## What is the difference between Strassen’s algorithm and divide and conquer?

The Divide and Conquer algorithm solves the problem in O (N log N) time. Strassen’s Algorithm is an efficient algorithm to multiply two matrices. A simple method to multiply two matrices needs 3 nested loops and is O (n^3).

What is the most encountered problem in competitive programming?

Now, Let us find a better approach to Competitive Programming. Please note: Run Time Error: It is the one of the most encountered problem by the beginners. The main reason could be : Segmentation Fault : It is the illegal accessing of memory address.
