Problem E
Both solutions that took AC on nowcoder returned YES YES NO for this input (below), but I think the correct answer is YES YES YES.
1 3C 3D 3H 5S
for example, 3S 5C 2C 2D 5D 5H makes draw.
And my code can't get AC. Could you check the judge? (sorry if correct)
Sorry, there was a mistake in the judge solution. Now it is fixed for this input.
By the way your code fails on
1 6H QH QC 6S
Wow,thanks! (update:get AC!)
well
Orz heltion, although heltion proposes few ideas in the official codeforces round,maybe he do not like to do this, but personally think his ideas are really good, I recommend everyone to solve them.
just out of curiosity. will the scoreboard of nowcoder be merged to gym?
I think the author does not have data for this competition.（The kind that can be exported directly）
