When we do swapping of head and tail

#1

when we do swapping of head and tail, we are swapping the whole node , so why does the data also doesn’t get swapped(10 and 50)

#2

the head and tail are pointers. head points to first node, tail points to last node. when we swap pointers, they will start pointing to different nodes, like head now points to last node while tail points to first node… nodes are not being swapped.

this is like int a =10,b=20; int *p = &a; p = &b;
here a is still same, but p now points to b.
