4.6. The following algorithm multiplies two nn matrices A and B and puts the answer in C. Let T(n) be the running time of the algorithm Find a simple function f(n) so that is (f(n)). MATRIXMULT( n,A,B,C) For i=1,,n For j=1,,n C(i,j)=0 For k=1,,n C(i,j)=C(i,j)+A(i,k)B(k,j) End for End for End for End 196
