More matrix shenanigans. I find the matrix, but then it asks me toThat's asking for me to do so with the initial matrix," Write the matrix that represents the number of communication links with exactly one intermediary computer."

A B C D

A 0 1 1 0

B 1 0 1 0

C 1 0 0 1

D 0 0 0 0

How the heck do I turn the # of intermediaries into a matrix?

What about for two intermediaries?
