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$)3$log$[3,3$n$]$

b$)$log$[2,$n$]$

c$)$n

d$)$nlogn

e$)$Power$[$n$,3]$

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

a$)$Nlogn

b$)$nlogn

c$)$Power$[$n$,3]$

d$)$loglogn

e$)$Power$[$n$,3/2]$
