The Hash Function Algorithm
Hashing transforms a "key" (like a word) into an integer index. This index tells us exactly where to store the corresponding "value" (the definition) in an array. Takes a string and returns an integer.
return 0; // key not found
return hash;
while (entry != NULL) if (strcmp(entry->key, key) == 0) if (prev == NULL) dict->table[index] = entry->next; else prev->next = entry->next; c program to implement dictionary using hashing algorithms

The worst case occurs when all keys hash to the same bucket. #include #include #include #define TABLE_SIZE 100 // Node
To build this, we need three structural components:
Maps that large integer into the range of our array size (using the modulo operator % ). This index tells us exactly where to store
// Structure to represent the Hash Table struct HashTable struct DictionaryItem* table[SIZE]; // Array of pointers to DictionaryItems ;
