This is a function to reverse a linked list recursively. Can someone please explain to me how this works?

1 typedef struct node 2 3 4 ) node; int data; struct node * next 6 node* eFunction (node* aNode) 7 if (aNode == NULL) return NULL; if (aNode-next-= NULL) return aNode ; 10 11 12 13 14 node * rest=eFunction (aNode-next); Node-next-next=aNode ; aNode-next= NULL; return rest
