Course details

Competitive Programming - Beginner

A brief summary

Solving a problem is meaningless if you can't convert it to a workable code in a contest that covers all the edge cases. Solving a problem, writing its code in an efficient language is a must for a problem solver. And currently, the fastest known coding language for a competitive programmer is undoubtedly C++.

We will go through each C++ concepts needed for a competitive programmer in order to ace in contests and problem solving.


Good logic sense. Familiarity with at least one programming language will even boost your learning, but it is not mandatory.

Course highlight

  • Learn to write codes in C++
  • Focus on writing small, concise, clean and efficient codes in C++ for complex problems
  • This course will prepare you for competitive programming and problem solving in C++.

What you will learn

You will be able to write efficient, bug-free codes in C++ for contests and your projects.

কম্পিটিটিভ প্রোগ্রামিং শুরুর জন্য এবং বিভিন্ন খুঁটিনাটি জানার জন্য এটি একটা ভালো কোর্স। কিন্তু একেবারে বিগিনার না হয়ে প্রবলেম সলভিং এ নূন্যতম কিছুটা এক্সপেরিয়েন্সড হলে ভালো হয় বলে মনে করি। এবং আমরা যারা কোনো বিষয়ে বেশিক্ষণ ধরে মনযোগ ধরে রাখতে পারিনা(থেমে থেমে কোনো কনসেপ্ট বুঝতে হয়) তাদের জন্য ভিডিও প্রভাইড করার কোনো ব্যবস্থা থাকলে খুবি ভালো হতো।

It was an amazing experience to learn and understand programming as well as problems. Our instructor Sadman Sakib vai was very friendly to us and always care about every point to improve our analytical abilities. The course was well organized and followed the basic beginner friendly syllabus. From this course one will learn how to solve a problem step by step and improve thinking style and also love programming.

বিগিনারদের জন্য কোর্সটা খুব উপকারী হবে। কিন্তু আগে থেকে প্রোগ্রামিং সম্পর্কে বেসিক না জানলে তাঁর জন্য একটু কষ্ট হবে। সাজিব ভাই খুব ভালো ক্লাস নিয়েছেন ।
