Hi everyone!↵

This is my second screencast, but this time with a webcam and some explanations at the end.↵
↵

I am posting this blog because I truly believe that most of you will find this screencast helpful and educative. ↵
↵

↵
#### **Reasons why you should watch this:**↵
↵
* To watch/learn how coders use stress test script to find bugs, sometimes to discover correct ideas to solution↵
* To watch the explanation to the problems ↵
* To start using new cool IDE from the video↵
* To watch me exciting and finally solving last problem on last minutes :D↵

All of my solutions passed final system testing, however problem D was removed from the contest because of some issues with checker program ([click](https://codeforces.net/blog/entry/78866?#comment-643650)).↵
↵
Finally, ranked 47th among 18k+ participants. ↵
