Ensures that a class has only one instance and provides a global point of access to it. Factory method pattern: Defines an interface for creating an object, but defers instantiation to subclasses. Abstract Factory pattern: Provides an interface for creating families of related or dependent objects without specifying their concrete classes ...
In computer science, a tree is a widely used abstract data type that represents a hierarchical tree structure with a set of connected nodes. Each node in the tree can be connected to many children (depending on the type of tree), but must be connected to exactly one parent, [ 1 ] [ 2 ] except for the root node, which has no parent (i.e., the ...

Executable files contain programs; all other files are also data files. However, executable files may also contain data used by the program which is built into the program.
