Moilanen's (1995) study of adolescent depression also attempts to validate Beck's theory in a new way, as Beck worked mostly with adults. Indeed, she found that the student's depression was often associated with dysfunctional beliefs and negative future attitudes.
A hash code is a numeric value that is used to insert and identify an object in a hash-based collection such as the Dictionary<TKey, TValue> class, the Hashtable class, or a type derived from the DictionaryBase class.
A hash function is a single, fully defined, computable function which takes as input bit sequences of arbitrary length, and outputs values of a fixed length r (e.g. r = 256 bits for SHA-256). There is no key, no family of function, just a unique function which anybody can compute.
