1. For each pseudo-code below derive the simplified asymptotic running time in Q(?) notation.

(1)

for 1 <-- .. n do

j <- 2

   while j <= n do j <-- j*j

(2)

for i <-- 1 .. n do

j <-- 1

    while j*j <= i do j <-- j + 1

Homework Answers

Answer #1

(1)

for 1 <-- .. n do

j <- 2

   while j <= n do j <-- j*j

Answer:O(n*√n)

Explanation:

The Outer loop runs for N time , while the inner loop runs for √n time. The Total time taken is n*√n => n3/2

=> O(n*√n)

(2)

for i <-- 1 .. n do

j <-- 1

    while j*j <= i do j <-- j + 1

Answer:O(n*√n)

Explanation:

The Outer loop runs for N time , while the inner loop runs for √n time. The Total time taken is n*√n => n3/2

=> O(n*√n)

Thanks, PLEASE COMMENT if there is any concern.

1.) the following code fragments give running time analysis (Big Oh). Explain your answer: sum2 = 0; sum5 = 0; for(i=1; i<=n/2; i++) { sum2 = sum + 2; } for(j=1; j<=n*n; j++) { sum5 = sum + 5; } i think it is O(n^2) since big oh finds the order of worst case which is the the second loop being n^2 complexity. but im not sure. 2.)
