Both dynamic programming and greedy algorithm are recursive algorithms, i.e., the global optimal solution is deduced from the local optimal solution (it is not considered from the whole optimal solution, always makes the best choice at present.) )

Test instructions: Gives a pile of points, the minimum value of the maximum distance from the point of origin to the end of all paths. (The meaning is oneself Baidu bar ...) ）Solution: Use the maximum value of the adjacent point as the weight value
