Question

a) When n = 2, how many times will "Hello class" be printed?
b) When n = 4, how many times will "Hello class" be printed?

c) What is the complexity function T(n) of this algorithm? Show proofs

for (i = 0; i<n; i++) {
printf("Hello class");}
for (j = 1; j < n²; j++) {
for (k = 0; k≤ n lg n; k++) {
printf("Hello class");}}
Transcribed Image Text:for (i = 0; i<n; i++) { printf("Hello class");} for (j = 1; j < n²; j++) { for (k = 0; k≤ n lg n; k++) { printf("Hello class");}}
Expert Solution
Step 1

There are 3 for loops in the above code, out of which one in inner for loop:

a) if n=2

15 times "Hello class" will print, I am assuming the base of log is 2.

 

b) if n= 4

149 time "Hello class" will print.
