This a simple program to find a Hamilton-circuit in a given diagram.

The program needs to modify the size of diagram which will be input to the program in advance.Modify the number of #define V 5 at line 3 to the size you want.That is how much point in your diagram.

use C++ compiler to compiler the program.

example diagram

Like the example diagram, you need to input the number if there is a road between any two points.After you finishes all the roads in the diagram, you need to input 0 0 to complete the data input.If there exists any Hamilton-Circuit,program will print out the cycle.
