Main topic:The gate is filled with trees of different heights, and every inquiry is if you cut down all trees with a height of no more than Q, then how many contiguous blocks are there?Thinking Analysis:Records the number of contiguous blocks left and right consecutively and used to maintain intervals.ThatSeg[num] = seg[numIf the middle part is connected, subtract one.#include Hdu 5200 Trees (offline line segment tree)
Line tree, TLE, various. Alas.... I'm so stupid.I use the line of the tree is the record left and right interval longest consecutive tree number ... Anyway, tle.#include This is the solution after looking at others, beautiful ah ...Sort the trees, sort the inquiries, and press the heights. Two pointer scan, for no higher than the height of the inquiry tree, its original position, if the left and right are not cut off, then the number of paragraphs +1, if all cut off, then the number of segment
