int index = hash_function(key) % table->size;
void destroy_table(HashTable *ht) if (!ht) return; for (size_t i = 0; i < ht->capacity; ++i) Node *cur = ht->buckets[i]; while (cur) Node *next = cur->next; free(cur->key); free(cur); cur = next; Distributes keys uniformly across the table to minimize
Inserting entries...
KeyValue *current = dict->table[index];
Entry *hashTable[TABLE_SIZE];
In the main function, notice the call to print_dictionary . Because we used Separate Chaining, you can visually see collisions. If "apple" and "banana" (hypothetically) hashed to the same index, the output would show:
// Search for keys printf("\nSearching for keys:\n"); int found; int value = search(dict, "banana", &found); if (found) printf("banana -> %d\n", value); else printf("banana not found\n");
When two unique keys yield identical hash indices, they are inserted sequentially into a linked list at that index. The program prepends new entries to the head of the bucket list ( new_node->next = dict->buckets[index] ), which executes in time complexity. 4.
