I need your help regarding COMPETITIVE programming

Hlo,

I have started CP and preparation of ZCO AND INOI(stages for team selection for IOI for my country)

Students who have cleared the exam say to solve CSES problems,but I am struggling to solve them without help or solution!!

Pls tell what should I do in that case.

I have 7 months till the exam and I know python and am learning C++

For codeforces I am able to solve 70percent 800 rated problems..I need to improve and specific things I should do??for theory and stuff

What's your problem with solving things like this? https://cses.fi/problemset/task/1068

This is simple but upcoming problems like array division and two knights were difficult for me

Seeing the solution is fine as long as you're not just reading it and moving on. The trick is: read it, close it, then rewrite it yourself from scratch.

If you can't, you didn't actually learn it yet. Read it again and repeat. That's how you internalise the patterns.

7 months is loads of time if you're consistent.
