this is the best way

div-1 begins from the violet color with 1650 ratings

now only russian tutorial is available, you may find it here and use google translator

из-за div-2 участников необходимо давать необоснованно простые две первые задачи в div-1 раунде, чтобы их даже div-2 участники смогли порешать, хотя большинство div-1 участников тратит на них 10-15 минут и, частенько, не решает больше ничего

так что же получается? div-2 участники обламывают фан div-1 участникам, а сами всё равно ничего не могут решить - не кажется ли это глупым?

и что? никто не отменяет div-2 only раунды

"for(int i=0;i<n;i++)"

you should write something like this:

"for(int i=0;i<14;i++)"

it is out of boundary error

and do not post your code here, please

I got too much messages like this: "wow, I love this contest! stories was interesting indeed!"

and I believe that any big story is not a trouble while problemsolving

of course, you may skip some parts of statement at your own risk but I believe you will spend no more than one minute for reading statement

it is possible to change statement for "given prime n and integer m, n < m, write YES if m is next prime after n otherwise write NO" but in this case statement is really dry, ungraceful and boring

I believe problem "Beavermuncher-0xFF" is really bad example

even you may not guess about unuseful parts you spend no more than one minute for read all statement and after that you may divide statement for useful and unuseful parts easily

let's waiting for rejudge

// reply for non-russian colleagues

what you think about this colouration? =)

but don't afraid, slowpoke is extremely slow ;)

i'm happy to read your messages :)

but you should understand that Codeforces is a russian project and some problem authors have extremely big troubles with english language

we are trying to make english statements are equal to russian but some bugs are inevitable, so we asks you to be more tolerancy

I believe the situation with english statements will improve with every new contest

You are not the first who let me out to a doctor =)
