I have solved 110 problems out of that I have solved only 20-25 problems on my own without taking any hint or reading any editorial....If I get stuck on a problem after 1-1.5 hrs I read the editorial or take hints from AI and even I couldn't understand the editorial after 40-45 min I ask AI to explain it...usually I try the problem and come up with a very different or weird solution which mostly gives WA 2... So I just wanted an help that what am I doing wrong?? Any valuable advice will be helpful?? ( I have started to learn discrete maths from kenneth rosen and I haven't started DSA I just know stl,two pointers,binary search) !!!

I am newbie and wanted an advice on how to get out of this WA on test 8...like how should I approach this so that I can solve it on my own ?
