What's the purpose in hashing information?

Question

After being taught how to create a hash table in class, I don\'t understand when hashing data would be useful. It seems to me that all hashing does is storing information in se

Answer 1

Have you ever used a dictionary or a set? They're typically implemented in terms of a hashtable because the value associated with a key can be found quickly.

{
'WA': 'Washington',
'WV': 'West Virginia',
'WY': 'Wyoming'
}
