C Program To Implement Dictionary Using Hashing Algorithms <No Ads>

hash table

In C, a dictionary is typically implemented using a , which maps unique keys to specific values. Since C doesn't have a built-in dictionary type like Python or Java, you must build one using an array and a hashing function. 1. Define the Data Structures

prev = curr; curr = curr->next;

unsigned long hash(const char *str, int table_size) unsigned long hash = 5381; int c; while ((c = *str++)) hash = ((hash << 5) + hash) + c; // hash * 33 + c c program to implement dictionary using hashing algorithms

Complexity

// Create new entry Entry *new_entry = (Entry*)malloc(sizeof(Entry)); new_entry->key = strdup(key); new_entry->value = strdup(value); new_entry->next = dict->buckets[index]; dict->buckets[index] = new_entry; dict->count++; hash table In C, a dictionary is typically

// Create a new item struct DictionaryItem* newItem = (struct DictionaryItem*)malloc(sizeof(struct DictionaryItem)); newItem->key = key; newItem->value = value; newItem->next = NULL; Define the Data Structures prev = curr; curr

key

A dictionary entry needs a , a value , and a pointer to the next entry in case of a hash collision.
