   How does a hash table work?

   • The Hash table data structure stores elements in key-value pairs where Value - data that are associated with keys. In a hash table, a new index is processed using the keys. And, the element corresponding to that key is stored in the index. This process is called hashing. Let k be a key and h (x) be a hash function.
