NOIP simulation 6

  Looked exam to see T1, that is the conclusion title, shook no results, went to see the second question,

  Meaning of the questions is clear, begged the smallest ring fixed point, not thinking problem solving strategies, and then think it is a water problem

  I called to find tarjan side double (said to be deep-fried but good average performance), the double edge in the demolition of violence while looking for the shortest path, we pay

  T3 looked that violence could get 10min hand, hit the back of ... violence T1 (what kind of logic I should not have to predict with confidence rerun it)

  After playing T1 violence like positive solution fails forcibly changed from n nmd ^ 4 only to make dp is independent of d, the retarded work most of the time spent

  Assignment before 30min, T1 violent evolution complete

  Assignment before 10min, T3 violence completion

  Before 10min, I think they came up with positive solutions T1, crazy play yards

  Former 2min, through the first five samples, 12,505,050 dead

  Assignment, T1 even with wa t 20, T2 100, T3 20

  Fortunately T1 ahead of playing violent, though they do not get the ideal of 30, but only if the sample had not written a "positive solution" then only 10 points

  Later want to find positive solutions to the complexity of the examination room although theory can be had, but require complex inclusion and exclusion, achieve no avail

  

  T1 promise that one day we agreed

  DP [i] [j] denotes the number of put together by the j-th day i biscuit embodiment, the number of combinations +

 

  T2 that day she left me

  Features logn using a binary split into groups, grouping the shortest run, rather than my n times

 

  T3 one day she will come back to me

  When the exam is hazy feeling graph theory, try to no avail

  The results indeed came up with a big cow on the map ...
