Hi,

Browsing through the problem set I found myself struggling to understand how people can get solutions up and running in such a short time whilst I'm here only able to solve A, B and sometimes C.

Seeing the fact that the hardest problems on Div2 usually require some advanced data structures that I've never heard of makes me question how people that were in my position managed to overcome this moment.

I was wondering if you could share any tips and tricks you used to skyrocket your rating and get past the Div2 hell.

What are some key steps that you tend to follow in the problem-solving process and also how did you manage to maintain your Div1 status after you made the step up?

I'm looking forward to hearing your stories on your competitive programming path from Div2 to Div1.

Happy coding! :D
