Hi fellow coder!

My friends and I usually agree on many topics but are have different views on how should one approach learning in Competitive programming.

My first friend says : " Solve virtual contests daily and you will learn all tricks and skills to improve"

My second friend says : " Solve different questions from different topics everyday and give virtual contests sparingly to learn and improve"

What I say : " Stick to one topic eg. Graphs or Binary Search for a week and try to solve all problems of that kind"

Now whose advice or method is the most optimum?

Which method do you follow?
