WebDec 9, 2013 · why are we doing the following: hash = ( (hash << 3) + n) % SIZE. This multiplies the prior value of hash by eight (shift by three is the same as multiplying by eight), adds the number of the letter, and then limits the value by obtaining the remainder of division by SIZE. Since the actual value of the hash code is of very little interest, as ... WebMar 5, 2024 · A hash map is a data structure allowing you to store key-value pairs. The key is used to look up the corresponding value, much like a word in a dictionary. Behind the scenes, hash maps use something called a hash function. This function takes the key as input and returns a hash code, a unique numeric value representing the key.
