DP
D [I] indicates that it takes at least a few steps from apartment to x-axis I .. P [I] the abscissa of building I, the ordinate of building I in H [I]
Note that the ordinate of Spiderman is always the height of the apartment !! So you don't need to worry about the ordinate !!
Traverse every building ..
The following requirements must be met when building I can be skipped from X coordinate J: (P [I]-j) ^ 2

Question Link
Spiderman sticks the Spiderman to a back-end building from the leftmost building. Then, the Spiderman hangs over and sends the spider silk until it reaches the last building. Ask at least a few splits.
Idea: Skip a building from x-axis J. I must meet the following requirements: (P [I]. x-j) * (p [I]. x-j)
So the state transition equation is: DP [2
Topic Link: Click to open the linkThe main topic: given the position of n buildings x and height y, Spider-Man from the first building to the last building to save people, to use the spider silk, every time to the same height, and in the process can not be rubbed to the ground, ask the least number of times to use the spider. (Enter in order of X)Data is too scary, by the coordinate DP, directly enumerate the scope of the building can control, find the minimum number of times to reach the coordi
