Assume the linked list of integers called head has the following values

$7112059$

if the following code is applied on the head, what is the output if we print the head

node$*ptr=$ head;

node $*p=$ NULL, $*q=$ NULL;

while $($ptr$!=$ NULL$)\{$

$q=ptr$ next;

$ptr$ next $=p$;

$p=ptr$;

$ptr=q$;

head $=P$;
