By jagan028, history, 3 days ago, In English

Hello cf community, I always get stuck at finding patterns if I have to create them from scratch, but other constructive problems around similar or even higher levels i can solve easily..

Eg of what I'm talking about:

Maybe i would feel much more confident and improve my intuition if I can solve similar problems, so please share if you have any construction-based problems that you feel is nice and tough!

    Exactly, I am stuck at it for more than an hour now but the difficulty is 900!?

    I cannot even approach; what is wrong with me :(

    Please share what were your first thoughts on seeing it

    Update: The sum is easy once you solve it(obviously) Takeaway is that I should not have gone with the mindset that it is hard!
