Hello everyone,

I want to invite you to participate in HackerEarth's Code Monk Contest where questions will be based on the topic Binary Indexed Tree. It is 3 hour long contest scheduled on 7th October. To check your timezone, click here.

The link to the contest: https://www.hackerearth.com/code-monk-binary-indexed-tree/

The problem set consists of 4 algorithmic tasks with partial solutions allowed — you get points for every test that your solution passes. The problem set was prepared by harshil. I am the tester and the editorials are presented by usaxena95.

Also, top 3 newbie winners to get HackerEarth T-shirts in each Code Monk challenge!
