I am confused about something. Whatever i post in codeforces blog, whether it is a funnier one, or tutorial one. I always get downvoted. I had to delete most of my previous post because of getting too many downvote. I wrote about a trick about segment tree a few days ago. I had to delete that too. :) Thanks.
I don't know if most of the codeforces user biased in giving vote by rating or not. Keep everyone demotivated by downvoting. :)
