Problem 2: For each of the problems below, the input has size n. For each piece of pseudo- code, give the O-estimate for its running time as a function of n. Include a brief informal explanation (at most 30 words). (a) (b) i←4 while in² do for k1 to i do b b + 15 i ← 3. i for k1 to 20 do b + b + 1 for 3 to n do for k3 to 5√n do j← 1 while j < 20 do a = a + 3 j+j+2 Problem 2: For each of the problems below, the input has size n.
