The following algorithms were given in Week 6 for computing the n power of a positive integer a. Use induction to prove that each of these algorithms is correct. (a) def pow(a, n) end if n=0 then 1 pow(a, n-1)*a (b) def pow(a, n) end if n = 0 then 1 pow(a, floor (n/2)) if n is even: x*x if n is odd: a*x*x
