Problem Statement
Let points, where there are not of them on a line, and consider the segments that are formed by connecting any of the points. There are enough colors available to paint the points and the segments, coloring them with the following two rules:
a) All the segments that reach the same point are painted of different colors.
b) Each point is painted a different color to all the segments that reach it.
Find the minimum number of colors needed to make such a coloring.
