I would like to share my little incident or I should say disaster because I didn't read the Codeforces Contest rules completely.
[problem:https://mirror.codeforces.com/contest/1658/problem/D1] [submission:https://mirror.codeforces.com/contest/1658/standings/friends/true#]
The incident : I solved the problem on the 58th minute in the contest, and then solved the hard version at 109th minute , now as I did not know the rule , I submitted the same solution of D2 again in D1 as I had suffered FSTs in a recent contest. Although I was sure that it will pass , I saw no harm in submitting again
And boom my rank fell down from around 270s to 500.
