20 minutes before the title look, feel increasing difficulty, T1 T2 will be apparent to the water 50 minutes, T3 is not determined correctly
T1 think positive solution, although n ^ 2 over hundreds of thousands very mysterious, but did not dare to fight violence,
Read to find the law 30 minutes played first point of 5 minutes, 20 minutes before it is clear that a second,
Then think of the positive solution, although n ^ 2 over hundreds of thousands very mysterious , but did not dare to fight violence,
For over counsels many cases, not counseling, do not hesitate to have ideas to dry, do not wear grumble
Qj did not get a score of 65, we should learn from lsc of "wisdom"
T2 rain tail, and the test had to turn over,
But the segment tree merge or think, ( to understand not deep )
T3 violence does not count, does not want, expect to see a sucker
Storm will not hit search, dp although positive solutions is also evident,
But I'm making a wrong decision ( to hide, in fact, is not too weak ), discard the T3
Exam time distribution (WD great God :)
200: 10 minutes to go over
the easiest out of 30 A (not back)
mid-35 + 20 (kill) (no positive solution,)
the most difficult
