Just 2 days ago I was accepted as a Microsoft intern for summer 2014. I'm so excited about this! And I really wanna say thanks to CF — interview questions were almost all about algorithms (although pretty basic) and CF was a place I improved so much! As you see, not so much time ago I was almost lightgreen.

As one of the reasons of my success I see this great platform — thanks MikeMirzayanov and thanks CF!

Hello everyone. If you participate in KPI-Open 2013 held now in Kiev I would like to talk about problems and their solutions in this post.

Our team was very unlucky today and we solved much less than we usually do (just 2 problems but with the fastest time). We had some strange bug in problem C. Our solution was based on storing coordinate shift to eliminate loops. We had WA on pretest number 8. Also we failed to do problem F, again because of not found bugs, but I think the idea was correct.

So tell about your solutions and share your ideas here.
