The use of “closed” vs. “open” reflects whether or not we are locked in to using a certain position or data structure (this is an extremely vague description, but hopefully the rest helps). For instance, the “open” in “open addressing” tells us the index (aka. address) at which an object will be stored in the … Read more

A Map is, conceptually, also just what it sounds like: a mapping from a set of objects (the distinct keys) to a collection of objects (the values). Hashtable and HashMap both implement Map, HashSet implements Set, and they all use hash codes … Read more
Python dictionary is a built-in type that supports key-value pairs. as well as using the dict keyword: or:
No. MD5 is not encryption (though it may be used as part of some encryption algorithms), it is a one way hash function. Much of the original data is actually “lost” as part of the transformation. Think about this: An MD5 is always 128 bits long. That means that there are 2128 possible MD5 hashes. … Read more
