Getting Started: Getting started with the sport of competitive programming প্রোগ্রামিং কনটেস্ট এবং অনলাইন জাজে হাতেখড়ি অ্যালগোরিদম কমপ্লেক্সিটি(বিগ “O” নোটেশন) Programming Language: To get start with competitive programming you must be comfortable with at least one programming language. We prefer C++ because it’s more beginner’s friendly and also more useful for programming contests. Here are few topics you must learn before you start programming contest.
