Hello sirs/madams/others,

I have recently noticed that I often struggle on B problems in division 2 contests I participate in. Moreover, they're often the last problem I manage to solve. Usually I read the problem incorrectly or miss a crucial observation and am thus unable to solve it. Do you guys have any tips I can use to overcome this obstacle?

UPDATE: So guys, this contest (edu 85) I tried to conquer this and solve B first, but it took too long and I didn't have enough time to work out the solution for F, the next easiest.

How do I get better?

Sincerely, praise kaunta

I used to have similar issues back when div2 contests were rated for me, but I was finally able to overcome them after learning how to codeblast.

In the previous contest I somehow ignored the statement i<j which changed the whole problem and eventually i solved B in the last.

Also has anyone else noticed this fact that most of successful hacks are usually in Div 2B.

My theory is that often for B they choose problems more or less simple, but they need to be less simple than the As. So they use A with problematic text/statement as B.

That makes the B especially hard for people with less english language understanding.

I solved B in one submit :)) I made several test cases to make sure my solution was correct. Initially, I had like 2-3 ideas that didn't work for non-sample tests. Of course, when I rush to submit, I forget to do this carefully.
