(Assignment 2, individual) Cyclic Linked list In cyclic_Il.c, complete the function has_cycle) to implement the following algorithm for checking if a singly-linked list has a cycle. Recall that if p is a pointer to a struct, p->member refers to a member variable in the struct, and is equivalent to (*p).member. 1. Start with two pointers at the head of the list 2. On each iteration, increment the first pointer by one node and the second pointer by two nodes. If it is not possible to do one or both because of a null pointer, then we know there is an end to the list and there is therefore no cycle 3. We know there is a cycle if a. The second pointer is the same as the first pointer b. The next node of the second pointer is pointed to by the first pointer The reason we know there is a cycle with the two conditions in 3) is that second pointer has wrapped around to the first one in the circle and we have detected it. After you have correctly implemented has_cycle, the program you get when you compile cyclic_Il.c will tell you that has_cycle agrees with what the program expected it to output
