Problem 1: Give an asymptotic estimate for the number h(n) of "Hello"s printed by Algorithm PRINTHellos below. Your solution must consist of the following steps: (a) First express h(n) using the summation notation . (b) Next, give a closed-form expression 1 for h(n). (c) Finally, give the asymptotic value of h(n) using the -notation. Show your work and include justification for each step. Algorithm PrintHellos ( n : integer) for i1 to n do for j1 to i2+i do print("Hello") for i1 to n2 do for j1 to i do print("Hello") Note: If you need any summation formulas for this problem, you are allowed to look them up. You do not need to prove them, you can just state in the assignment when you use them
