1 write a function that finds the length of a list of list node t nodes function pro 5346969
1. Write a function that finds the length of a list of list_node_t nodes.
Function prototype:
int length(list_node_t *headp);
2. Write a recursive version of function search (see iterative function search on page 721)
prototype:
list_node_t *search(list_node_t *headp, int target);
Searches a list for a specified target value. Returns a pointer to the first node containing target if found. Otherwise returns NULL.
type list_node_t is typedefed on page 716:
typedef struct list_node_s {
int digit;
struct list_node_s *restp;
} list_node_t;
