When I was new to competitive programming, I saw a video in topcoder of the topcoder open 2006 and it freaking inspired me to compete more.
In that tomek was champion.
How it happened?
tomek solves 250 and petr does it too.
petr solves 500 quickly and tomek realized he can’t win if he don’t solve 1000. So tomek closes his 500 and opens the 1000. And solves it! He takes a lead by a little points.
scoreboard
….....…250 500 1000
tomek…s…_____…s
petr….s..._…__s
During challenge phase petr challenged so many that he got lead over tomek.
….....…250 500 1000 challenges
petr….s...…__s ..,.….......__...many
tomek…s…_____…s.......... none
tomek didn’t know what to do, since he knew he wouldn’t be champ… just 20 seconds remaining for challenges to be over, he opened a random problem with a random test case and “it had a memory error I don’t know where” (he said later), he got the lead again! He became the TCO 2006 champion. LIKE WHAAT?..
This video, blew my brains out and I got hooked to cp like forever. I can’t find that video, its not in youtube either 
I also wanted to watch it. Maybe asking
