In yesterday div 2 contest I submitted two solutions for 3rd question named rotation matching. I got 1050 pts for 1 st submition and 750 for 2nd submition.Why did you skipped my best submition and accepted the second submition , becauseit gave me 750 pts which increased my rank and decreased my rating.can any one explain?
you lose points if you resubmit, so your first one got skipped because ur 2nd one passed pretests as well
Imagine that your first solution was wrong. So, which one to consider?
Why send a solution again if the first isn't wrong?
Considering this, the best aproach to codeforces is consider the last submission.
