allocate_schedule(4)                                                            
                                                       
                                                                                
                                                       
may return:                                                                     
                                                       
                                                                                
                                                       
[[1,0,3,2],[2,3,0,1],[3,2,1,0]]; 

For Day one the array is [1,0,3,2].

Team 0 looks at the first entry to see who they play.  The first entry in
[1,0,3,2] is a 1, so they play team 1.

Team 1 looks at the second entry to see who they play.  The second entry
in [1,0,3,2] is a 0, so they play team 0.

Team 2 looks at the third entry to see who they play.  The third entry in 
[1,0,3,2] is a 3, so they play team 3.

Team 3 looks at the last entry to see who they play.  The last entry in 
[1,0,3,2] is a 2, so they play team 2.

For Day two the array is [2,3,0,1] ...

Team 0 and 2 play each other.
Team 1 and 3 play each other.

HTH,
