An ORDER BY clause in SQL specifies that a SQL SELECT statement returns a result set with the rows being sorted by the values of one or more columns. The sort criteria does not have to be included in the result set (restrictions apply for SELECT DISTINCT , GROUP BY , UNION [DISTINCT] , EXCEPT [DISTINCT] and INTERSECT [DISTINCT] .)
This is a list of all airline codes. The table lists the IATA airline designators , the ICAO airline designators and the airline call signs (telephony designator). Historical assignments are also included for completeness.
Depth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) and explores as far as possible along each branch before backtracking.
In computer science, tree traversal (also known as tree search and walking the tree) is a form of graph traversal and refers to the process of visiting (e.g. retrieving, updating, or deleting) each node in a tree data structure, exactly once.
Merge sort. In computer science, a sorting algorithm is an algorithm that puts elements of a list into an order.The most frequently used orders are numerical order and lexicographical order, and either ascending or descending.
In computer science, arranging in an ordered sequence is called "sorting".Sorting is a common operation in many applications, and efficient algorithms have been developed to perform it.
The squadron code is usually presented along with an individual letter or character to form a call sign for the particular aircraft. Location of the call sign combination has usually been on the rear fuselage next to the RAF roundel. In instances when an unusually large numbers of aircraft comprise the squadron, multiple squadron codes have ...
The acronym's procedural application does not match experts' intuitive understanding of mathematical notation: mathematical notation indicates groupings in ways other than parentheses or brackets and a mathematical expression is a tree-like hierarchy rather than a linearly "ordered" structure; furthermore, there is no single order by which ...
