Hi, fellow Coders.
I am glad to invite you to join the amazing math contest Infinitum April'14, a monthly contest restricted to mathematics domain, held on HackerRank.
Register at https://www.hackerrank.com/infinitum-apr14
It's a 4 day contest with 6 problems, out of which 2 are written by me. Problem statements are available in English, Russian and Chinese.
You can view the last month's challenges here: https://www.hackerrank.com/infinitum-mar14/challenges This month, the problems are much more interesting, have more variety and are a little more difficult.
Looking forward to your participation. If you have queries, feel free to ask here.
Update: Just 3 more days left.
