4. (20 pts) Considering the pseudo code below, answer the following three questions: for (i=0;in;i++){ printf("Hello class"); } for (j=1;jn2;j++){ for (k=0;knlgn;k++){ printf("Hello class"); }} a) (5 pts) When n=2, how many times will "Hello class" be printed? b) (5 pts) When n=4, how many times will "Hello class" be printed? c) ( 10 pts) Drive the complexity function T(n) of this algorithm
