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 (rhythmic gymnastics)

Rope (rhythmic gymnastics) may be made of hemp or a synthetic material which retains the qualities of lightness and suppleness. Its length is in proportion to the size of the gymnast. The rope should, when held down by the feet, reach both of the gymnasts' armpits. One or two knots at each end are for keeping hold of the rope while doing the routine. At the ends (to the exclusion of all other parts of the rope) an anti-slip material, either coloured or neutral may cover a maximum of 10 cm (3.94 in). The rope must be coloured, either all or partially. It may be either of a uniform diameter or be progressively thicker in the center provided that this thickening is of the same material as the rope.

The fundamental requirements of a rope routine include leaps and skipping. Other elements include swings, throws, circles, rotations and figures of eight.

Allison is finally out of her coma after suffering from a brain tumor on her brain stem and at first she can barely use her right hand, but as the season progresses she gets better and better. For the first few episodes Mrs. DuBois walks with a cane and does physical therapy. She got to keep her gift because she delayed the surgery from season 5 at the very end to catch Oswaldo Castillo. Allison's friend who was in the hospital with her (played by Martha Plimpton) dies under mysterious circumstances and Allison realizes it was the doctor who saved her life. The Halloween episode Bite Me is a take on Night of the Living Dead where Allison uses her dream to catch a killer no one would never suspect. Another greedy doctor creates a vaccine hoping to make millions by infecting people, but the courageous guy that the doctor gave it to, killed himself. Joe gets a new job, but to his dismay he gets to work with a very eccentric leader played by Joel Moore. After Terry (Joe's last boss) sold the company, the people that bought it out wanted to keep Joe on working thee days a week in San Diego, but when Allison got sick he had to resign his position. By now, all three girls are growing up with Ariel graduating high school. Allison learns a valuable lesson in one episode where she tries desperately to get Ariel to do the things she does, but soon realizes, Ariel has to live her life and move on and the college she wants to attend is Dartmouth College in New Hampshire.
