Competitive Programming - Beginner - B11
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.

Who Can Join This Course?

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

Assalamualikum. Alhamdulillah. Devskill's every course is awesome. In this course, our instructor was Sadman Sakib Bhaiya. Sakib Bhaiya has taken the class very sincerity. He has covered each topic in the easiest way. This course was very helpful for me. I have learned many things from this course.

একদম বেসিক থেকেই শুরু হয় তবে c/c++ একটি ভাষায় কিছুটা নলেজ থাকলে ভালো।কোর্স ইন্সট্রাক্টর সাদমান সাকিব ভাইয়া অসাধারণ একজন মানুষ।এককথায় well-planned অসাধারণ একটি কোর্স।
