Hey, I have been practicing problems from the problemset and also gave regular contests hosted on codeforces. During the beginning I struggled to even submit the A problem in contests. So I thought I should first hone my brute force and implementation skills. I solved over 400+ problems from codeforces problemset. But even still, I struggle to submit A and B problems of Div. 2 contests and sometimes even Div. 3 contests. I can't figure out what is wrong with my way of practice or maybe the way I think about problems.
Any kind of advice would help me.
Thanking you in advance
