Note: the find_x function in this question is also used in the next question.
Nodes in a singly-linked list are instances of type node_t:
typedef struct node {
int data;
struct node *next;
} node_t;
Here is the declaration for a recursive function named find_x, which searches the
linked list pointed to by head and returns the count of the number of times x is
found:
int find_x(node_t *head, int x);
What is the C code for the base case?
Oif (head == NULL) {
return 1;
}
Oif (head == NULL) {
return 0;
}
Oif (head->data == x) {
return 1;
}
Oif (head->next == NULL) {
return 0;

What does function mystery do?
int mystery (int m, int n)
{
if (mn) {
return n;
} else {
return m + mystery(m + 1, n);
}
}
O When called with arguments m= 1 and n >= m, it returns nx(n+1) / 2
When called with arguments m= 1 and n >= m, it returns nt; that is, the factorial
of n.
When called with arguments m >= 1 and n>= 1, it returns mx n.
When called with arguments m<n and n>= m, it returns
-m+1)
