Dynamic set structures typically add: create(): creates a new, initially empty set structure. create_with_capacity(n): creates a new set structure, initially empty but capable of holding up to n elements. add(S,x): adds the element x to S, if it is not present already. remove(S, x): removes the element x from S, if it is present.
In computer science, a heap is a tree -based data structure that satisfies the heap property: In a max heap, for any given node C, if P is a parent node of C, then the key (the value) of P is greater than or equal to the key of C. In a min heap, the key of P is less than or equal to the key of C. [ 1] The node at the "top" of the heap (with no ...
Intersection (set theory) The intersection of two sets and represented by circles. is in red. The intersection of and is the set of elements that lie in both set and set . In set theory, the intersection of two sets and denoted by [ 1] is the set containing all elements of that also belong to or equivalently, all elements of that also belong to ...
The empty set is the set containing no elements. In mathematics, the empty set is the unique set having no elements; its size or cardinality (count of elements in a set) is zero. [ 1] Some axiomatic set theories ensure that the empty set exists by including an axiom of empty set, while in other theories, its existence can be deduced.
Space. Θ ( n) [ 1] O ( n) A small phone book as a hash table. In computing, a hash table is a data structure often used to implement the map (a.k.a. dictionary or associative array) abstract data type. A hash table uses a hash function to compute an index, also called a hash code, into an array of buckets or slots, from which the desired value ...
t. e. In computer science, a for-loop or for loop is a control flow statement for specifying iteration. Specifically, a for-loop functions by running a section of code repeatedly until a certain condition has been satisfied. For-loops have two parts: a header and a body. The header defines the iteration and the body is the code that is executed ...
Furthermore, one sometimes considers set theories in which there are no infinite sets, and then the axiom of empty set may still be required. However, any axiom of set theory or logic that implies the existence of any set will imply the existence of the empty set, if one has the axiom schema of separation. This is true, since the empty set is a ...
In mathematics, specifically set theory, the Cartesian product of two sets A and B, denoted A × B, is the set of all ordered pairs (a, b) where a is in A and b is in B. [ 1] In terms of set-builder notation, that is [ 2][ 3] A table can be created by taking the Cartesian product of a set of rows and a set of columns.
