Question

6. Create a class Fact. Each Fact has an integer ID. Ever Fact also has a list of Fact pointers. Ask the user for an integer N which is the number of Facts to be generated. After all of them are generated and added to a list, go back through and add a random number 0 to 5 Fact pointers to EACH of them. This creates a rather complex mesh of Facts. Display your mesh, then choose one of them at random and display all reachable facts. Do not report loops. For example


If the user enters N = 8

And the following Facts are created randomly:
#1 -> 2, 5
#2 -> none
#3 -> 4, 5, 7
#4 ->3, 6
#5 ->7
#6 ->1
#7 ->2

IF
#4 is chosen the result would be
#4 ->3, 6, 5, 7, 1, 2

since
4 connects to 3 and 6
3 connects to 4 , 5, 7
6 connects to 1
5 connects to 7
7 connects to 2
1 connects to 2, 5
2 connects to none

IF
#1 is chosen
The result would be
#1 ->2, 5, 7

Since
1 connects to 2, 5
2->none
5 connects to 7
7 connects to 2
