3. (a) Consider the procedure procedure Loopsl (n, a positive integer) 1, for i=1 to n 2. for j =i to n print (i,j) i. In terms of n, how many ordered pairs are printed? ii. What is the runtime in notation of this procedure? (b) Consider the procedure procedure Loops2 (n, a positive integer) 1, for k= 1 to n-2 2. for i = k + 1 to n-1 for j=i+ 1 to n print (i,j) 4. i. In terms of n, how many ordered pairs are printed? ii. What is the runtime in notation of this procedure? (c) Consider the procedure procedure Loops3(n, a power of 2) 1. for i -1 to n 2. while j 1 print (i,j) 4. 5. i. In terms of n, how many ordered pairs are printed? ii. What is the runtime in notation of this procedure
