Graph Theory explosion hammer field!
When the warm-up match
A palindrome
B? CF a particular problem? FFT? Bitset?, Ah, this seems Boss
C, in which the feeling oj seen,
D, analog? Should not be that way, otherwise how could no one A yet.
I began to feel a bit wrong, and sure enough, after a while began to list partition blocks
After the game, a group, B title Bitset, I heard someone question D violence hit the table, also the A, woc, nb, C is the DP title
Official Game
Go first to sign, graph theory, graph theory, trees, graph theory...? ? ?
I? ? ? What is this, such a structure thing?
After a long start n, B out A title
K problem? Well this question sign? A out why so many people, sentenced to enumerate a subset of parity ring so well written? ? ? ? ?
E is the spanning tree thing? (Yes)
D problem is the tree? ? ? Do not get me Yeah, this is not a tree diagram ...., a little nervous ah
J segment tree, how to maintain it does not T? ? ?
woc, first try it, if passed it (mind a little nervous, did not have to completely cool)
After the game
On this chart. . . The last point I have confidence oppressive gone, TLE, WA, I ,,, school game how to play? This state is really not suitable for playing school Messiah,
