Consider the matrix multiplication C = AB. A matrix W is called a witness matrix with the following conditions:


• If ci j = 0, then wi j = 0.
• If ci j = 1, then wi j = k where aik = bkj = 1.


make code to displays two Booelan matrices A and B and their product
C. Note that we define these matrices with 0 and 1 entries and declare their types
as boolean with dtype = bool statement after specifying the entries. Alternatively,
we could have specified theses matrices with True and False entries. The boolean
product C is then converted to integer by the astype method and both forms of C
