Hi,

Can anyone help me with this problem?

You are given an array with n integers a₁, a₂, ..., a_n , a integer K and m queries.

There are two types of query:

1. give you two integers l and r and ask you to print how many number of integers a_l, a_l + 1, ..., a_r which equal to K.

2. give you three integers l, r and v and ask you to add the value of a_l, a_l + 1, ..., a_r by v.

You should print the answer of the first queries.

Thanks, Sorry for my bad English!

Hi All,

I see something strange in http://mirror.codeforces.com/contestRegistrants/613...

Is it a codeforces bug?

Hi Codeforces,

BWC(Black.White Crow) Round #5 is going to take place on BWC At 6 PM this Friday.(Tehran Timezone).Problem statements are in Perisan.

This Contest will have 5 problems and each of them has some subtasks. Each subtask is a short answer algorithmic problem(Like Project Euler). The problems will be easy. Writer of the Round is me (ATofighi). I'd like to thank strange_voice for testing the Contest.

Good luck and Have fun.

Hi Codeforces!

Do you see it?

I like it!

Thanks MikeMirzayanov and Codeforces team!
