Please debug the following program and answer the following questions. There is a cycle in a linked
list if some node in the list can be reached again by continuously following the next pointer.
#include
typedef struct node {
int value;

} node;
int 11_has_cycle (node *first)
if (first
==
node *head =

NULL) return 0;
first;
while (head->next != NULL) {

if (head
first) {
return 1; }
head = head->next;
return 0;
void test ll_has_cycle () {
int i;
