Rope (data structure)

In computer programming, a rope, or cord, is a data structure composed of smaller strings that is used for efficiently storing and manipulating a very long string. For example, a text editing program may use a rope to represent the text being edited, so that operations such as insertion, deletion, and random access can be done efficiently.

Description

A rope is a binary tree having leaf nodes that contain a short string. Each node has a weight value equal to the length of its string plus the sum of all leaf nodes' weight in its left subtree, namely the weight of a node is the total string length in its left subtree for a non-leaf node, or the string length of itself for a leaf node. Thus a node with two children divides the whole string into two parts: the left subtree stores the first part of the string. The right subtree stores the second part and its weight is the sum of the left child's weight and the length of its contained string.

The binary tree can be seen as several levels of nodes. The bottom level contains all the nodes that contain a string. Higher levels have fewer and fewer nodes. The top level consists of a single "root" node. The rope is built by putting the nodes with short strings in the bottom level, then attaching a random half of the nodes to parent nodes in the next level.

Rope (play)

Rope is a 1929 British play by Patrick Hamilton. In formal terms, it is a well-made play with a three-act dramatic structure that adheres to the classical unities. Its action is continuous, punctuated only by the curtain fall at the end of each act. It may also be considered a thriller whose gruesome subject matter invites comparison to the Grand Guignol style of theatre. Samuel French published the play in 1929.

Plot and setting

The play is set on the first floor of a house in Mayfair, London in 1929. The story, thought to be based loosely on the Leopold and Loeb murder case, concerns two young university students, Wyndham Brandon and Charles Granillo (whom Brandon calls "Granno"), who have murdered fellow student Ronald Kentley as an expression of their supposed intellectual superiority. At the beginning of the play they hide Kentley's body in a chest. They proceed to host a party for his friends and family at which the chest containing his corpse is used to serve a buffet.

Production history

Rope (1957 film)

Rope is a 1957 Australian television film. Broadcast live in Sydney, it was kinescoped/telerecorded for showing in Melbourne (these were the only Australian cities with TV at the time). Based on the play by Patrick Hamilton, it aired in a 70-minute time-slot on non-commercial ABC, and was a drama about two people who had committed murder. Full cast listing is unavailable, but the cast included John Meillon, Bruce Beeby and Don Pascoe. It was produced by William Sterling. According to an article in the 19 September 1957 edition of The Age, the broadcast was well received by viewers during its Sydney telecast, and producer Sterling was happy with the quality of the kinescope/telerecording.

Introduction (music)

In music, the introduction is a passage or section which opens a movement or a separate piece, preceding the theme or lyrics. In popular music this is often abbreviated as intro. The introduction establishes melodic, harmonic, and/or rhythmic material related to the main body of a piece.

Introductions may consist of an ostinato that is used in the following music, an important chord or progression that establishes the tonality and groove for the following music, or they may be important but disguised or out-of-context motivic or thematic material. As such the introduction may be the first statement of primary or other important material, may be related to but different from the primary or other important material, or may bear little relation to any other material.

A common introduction to a rubato ballad is a dominant seventh chord with fermata, Play  an introduction that works for many songs is the last four or eight measures of the song, Play  while a common introduction to the twelve-bar blues is a single chorus. Play
