Code not working

#1

Code is not working. May be any infinite loop/recursion is there.

#2

There’s some error in your mid point function only, try solving the segmentation error in that, also would like to give you a better approach to find mid point of a linked list:-

node* midpoint(node* head){
node* slow = head, *fast = head->next;
while(slow && fast && fast->next)
{
slow = slow->next;
fast = fast->next->next;
}
return slow;
}
