Cоnsider the fоllоwing C implementаtion of а hаsh table: #include#define HASH_SIZE 10struct bucket { char* string; struct bucket* next;};typedef struct bucket Bucket;Bucket table[HASH_SIZE];//hash table... unsigned hash(char* key) { unsigned val = 0; while (*key) val = *(key++) + 2 * val; return val % HASH_SIZE;}void init() {//initialize the buckets of my hash table... int i; for (i = 0; i < HASH_SIZE;i++) table[i].string = NULL;}void printHashTable() { int i = 0; Bucket* iterator; for (; i < HASH_SIZE; i++) if (table[i].string) {//not an empty bucket iterator = &table[i];//head of linked list while (iterator) { printf("%sn", iterator->string); iterator = iterator->next;//advances the iterator... } }}int insert(char* word) { if (search(word)) return 0;//duplicate value, do not add it to the hash table! unsigned index = hash(word); if (table[index].string == NULL) {//empty bucket table[index].string = (char*)malloc(strlen(word) + 1); strcpy(table[index].string, word); table[index].next = NULL; return 1;//successful insert } char* currentHeadOfLinkedList = table[index].next; table[index].next = (Bucket*)malloc(sizeof(Bucket)); table[index].next->string = (char*)malloc(strlen(word) + 1); strcpy(table[index].next->string, word); table[index].next->next = currentHeadOfLinkedList; return 1;}int search(char* word) {//returns 1 if successful and 0 if not int i = hash(word); Bucket* iterator;//link list iterator... if (table[i].string) {//not an empty bucket iterator = table + i;//head of linked list while (iterator) { if (!strcmp(iterator->string, word))//matched return 1; iterator = iterator->next; } } return 0;//unsuccessful search} Also, assume that the following main function uses the hash table to store some strings: main() { int i; init(); char* strings[] = { "AB", "CD", "EF", "GH", "CD" }; for (i = 0; i < 5;i++) insert(strings[i]); printHashTable();} Answer the following questions: (10 points) Find the hash value of every member of the strings array. The hash value is calculated and returned by the hash function (Hint: ASCII values of letters A, B, C, ... are 65, 66, 67, etc.) (10 points) What's the output of the given C program.
