The main idea: given a sequence, several times to dye an interval into a color, to find out what the last point of the colormSince the dye works for each point is only the last one, so do it backwards, and if a point has been dyed, just check the point and connect it to the right.So each point will only be stained once, time complexity O (n+m)#include Bzoj 2054 crazy steamed buns and check set

Then the weight of the regiment and the number of points in the regiment are recorded at the topmost ancestor of the regiment. Then each time the greedy find out (weights and/points) the largest group.
