How to get the new ideas & When should I look at the editorial. (You can avoid spoilers, not a must read)
I tried hard to solve the Problem G
I've spent 30 minutes trying it, and I'm already out of ideas.
My fear
What I usually try to do is "I will try for another 15-20 minutes then I will try again tomorrow and I will look at the editorial."
Any slight hints/ideas or anything on how to face the situation that I'm facing these days would be greatly appreciated.
My Goal
Sorry
As a newbie, I would say spend more time solving harder problems, and if you still can't figure it out. Look at the solution. It will deepen your understanding.
What really helps is watching the livestreams of the contests.
Not all techniques have names. Many techniques are not listed anywhere. The only way to know them is from someone more experienced. If you don't have such people around you, livestreams are all you have. And they should be good enough.
Don't fall in the trap of automatically assuming that hard problems can only be solved with some algorithm or technique you don't know. Sure, there are many unnamed techniques, but you can often come up with them if you think hard enough. Look at the editorial only when you stop making progress and/or getting ideas.
