1. Consider the statements below, where the variables m and n are assumed to have integer values, with n > 0, and let W denote the while-loop in these statements. a := m; b:= n; c=0; while b>0 do if 2 b then a := 2a; b:=b/2; else c:= c+a; b:=b-1; fi; od; (a) (30p) Prove that ab +c=mn is a loop invariant for W
