Web3.4 Hash Tables. If keys are small integers, we can use an array to implement a symbol table, by interpreting the key as an array index so that we can store the value associated with key i in array position i. In this section, we consider hashing, an extension of this simple method that handles more complicated types of keys. WebJul 16, 2009 · 8. For strings, the Judy Array might be good. A Judy array is a complex but very fast associative array data structure for storing and looking up values using integer or string keys.
