1. How to write a code to describe the adjacent? its all different with different side length

[rmxhaha]

Just put it in array of the maximum length

level 0 = 1 member
level 1 = 3 member
level 2 = 5 member
ans so on

const int max_level = 6;

int colors[ max_level ][ max_level * 2 - 1 ];

is that what you're asking ?

I don't think so. I think he's asking how to solve the problem. I'll give you a hint; start by opening the input file and reading each line and parsing each line contents into a vector of a struct/class of your own definition. That'll be a start...
