A number greater than B and a number less than B can cancel each other out, so we use 1 and 1 to denote.Extending from B to both sides, left[i] means that the left side of B has a number of possible numbers of I smaller than B, and Right[i] indicates that the B-right offset has the number of I numbers larger than B.Ans=sigma (Left[i]*right[i]).#include "bzoj1303" [CQOI2009] median figure

Test instructions: There is a non-direction graph and three colors, the number of vertices nIdea: If the time complexity of direct violence is 3^n, obviously can't bear.Considering any one node u, then the sub-graph of all the points in S (U) is unicom and the points in S (U) can only dye the other two colors, because the graph is connected, so the dyeing scheme is definitely unique, that is, we have a two-point graph for each node dyeing, if there is a conflict then there is no scheme.

Title Link: BZOJ-1303Problem analysisFirst, locate position Pos for B, and then assign the value of less than B in the sequence to-1, and the value greater than B is assigned to 1.Expand from B to the left, keep counting Sum[i, b-1], and then add one to Cnt[sum[i, b-1], so that the Sum of each left is the number of values.then expand from B to the right, counting Sum[b + 1, i], then Ans + = cnt[sum[b + 1, I]].Code#include [Bzoj 1303] [CQOI2009] Median figu

In other words, she knows which cards Adam have on the table before he turns them face up. Using This information she orders hers own cards so, she gets as many points as possible.Your task
