The great spirit show singly linked lists-CodePudding

Input and output contains five singly linked list of nodes, why I write only input, but can't output? Refer to

Changed after the output, but seems to be wrong

Your head to the p (head=p)
Point p and q (p=q);
List at the end of q - the link=null, which is equivalent to the head=null
Your head have been changed, so there is no output,
