In a cypher Neo4j, if there was a database about movies. There are nodes about actors, movies, and genres. Actors play in movies, movies have various genres actors have preference in genres. If there are edges that indicate the relationship between actors as a FRIEND and we want to return the result that shows the name of the David's (in actor node) friend who played in Superman(movies node) what query do I have to use? Just telling me the format is fine. What I want to know is how to display the result of the edge that connects the same nodes, in this case, actors--actors as a friend.

Hash Table

A hash table also called a hash map, is a data structure that maps key-value pairs. The hash table can be used in complex systems to provide fast access and compact storage. A hash table is a structure that stores data in an abstract data type kind of associative array. It keeps data in an array format, with a distinct index value for every data value. If the index of the required data is known, then the data can be accessed very easily.
