How would you modify Strassen’s algorithm to multiply n×n matrices in which n is not an exact power of 2? Show that the resulting algorithm runs in time Θ(n^lg7).
Determine φ (m), for m=12,15, 26, according to the definition: Check for each positive integer n smaller m whether gcd(n,m) = 1. (You do not have to apply Euclid’s algorithm.)
If d(n) is odd, show that n is square.
