Rightend

Rightend, often written as "right end" or in code as RightEnd, is a general term used across disciplines to denote the boundary or terminal point located on the right-hand side of a object, set, sequence, or spatial figure. It is not tied to a single formal definition, but rather serves as a directional reference in context.

In mathematics and geometry, the right end typically refers to the right endpoint of an interval or the rightmost point of a shape. For a real interval [a, b], b is the right endpoint; for (a, b], b serves as the right boundary of the set, though it may not be included depending on the interval notation. In graphs and coordinate geometry, the right end designates the point with the greatest x-coordinate within a given region, assuming standard orientation.

In computer science and data structures, the right end often indicates the tail or end of a sequence, list, or deque. Operations may add or remove elements at the right end (for example, pushRight or popRight in certain implementations). In practice, the concept also appears in string and text processing, where the right end of a string is the trailing portion, and functions may trim or examine characters from the right end (right trim, rightmost character).

The term is largely contextual; it may be used informally to describe any rightward boundary or terminal position in a given domain. It is commonly contrasted with the left end or leftmost point.
