C Queue, Duplicating elements in sorted order -

so

if have queue

a --> b --> null;

and when utilize function

void duplicate(queuenodeptr phead, queuenodeptr *ptail)

it give

a --> --> b --> b --> null

i can't around head sorting reference of tail.

all

a --> b --> --> b --> null

how approach this?

basic code fine need hint,

thanks!

if can find out number of elements in queue (n), can following:

for = 1 n e = remove(queue) insert(queue, e) insert(queue, e)

you each element duplicated using queue operations.

if want manipulate info directly, it's no longer queue - it's (linked) list.
