If a computer network of $10$ servers with star shape$($circular and one center$)$ and one main server

is desired what is the complexity of linear network?

a$)3lo{g}_{3}3n$

b$)log2n$

c$)n$

d$)$ nlogn

e$)n^3$

In the above question if they are lined up in double linked list what is the average complexity?

a$)$ N

b$)$ nlogn

c$)n^3$

d$)loglogn$

e$)n^{\frac{3}{2}}$
