Problem 2254. Possible Opponents Matrix for single-elimination tournament

Difficulty:

It's tournament time!

Given a single-elimination tournament with 2^N competitors, compute the 2^N by 2^N matrix M such that M(i,j)=1 iff competitor i might play competitor j in round R, where 1<=R<=N. (In each round each surviving competitor plays his "next door neighbor" in the bracket.)

For example, if N=1, R=1 then

 M =
   [ 0 1
     1 0]

or if N=2, R=2 then

 M = 
   [ 0 0 1 1 
     0 0 1 1
     1 1 0 0 
     1 1 0 0 ]
