Tree (data structure)

In computer science, a tree is a widely used abstract data type (ADT)--or data structure implementing this ADT--that simulates a hierarchical tree structure, with a root value and subtrees of children with a parent node, represented as a set of linked nodes.

A tree data structure can be defined recursively (locally) as a collection of nodes (starting at a root node), where each node is a data structure consisting of a value, together with a list of references to nodes (the "children"), with the constraints that no reference is duplicated, and none points to the root.

Alternatively, a tree can be defined abstractly as a whole (globally) as an ordered tree, with a value assigned to each node. Both these perspectives are useful: while a tree can be analyzed mathematically as a whole, when actually represented as a data structure it is usually represented and worked with separately by node (rather than as a list of nodes and an adjacency list of edges between nodes, as one may represent a digraph, for instance). For example, looking at a tree as a whole, one can talk about "the parent node" of a given node, but in general as a data structure a given node only contains the list of its children, but does not contain a reference to its parent (if any).

Tree (Gaelic Storm album)

Tree is a 2001 album by Gaelic Storm.

Track listing

Beggarman, Black is the Colour, New York Girl, An Poc Ar Buile, and Go Home Girl are traditionals. Beggarman, which is played fast, is a standard in their live set list and features a didgeridoo very prominently. Black is the Colour, sung by guitarist Steve Twigger, is very slow and mournful, reminiscent of the original composition from the previous album She Was the Prize. An Poc Ar Buile is the band's first venture in the Irish language. The song is normally slowly sung, but Gaelic Storm puts a twist into it by singing it fast, complete with hoots and hollers. Go Home, Girl is a faster tune about a girl who falls in love with a gypsy, only to have her advances turned down for an ironic reason.

Illinois

Illinois (ⁱ/ˌɪlᵻˈnɔɪ/ IL-i-NOY) is a state in the midwestern region of the United States. It is the 5th most populous state and 25th largest state in terms of land area, and is often noted as a microcosm of the entire country. With Chicago in the northeast, small industrial cities and great agricultural productivity in central and northern Illinois, and natural resources like coal, timber, and petroleum in the south, Illinois has a diverse economic base and is a major transportation hub. The Port of Chicago connects the state to other global ports from the Great Lakes, via the Saint Lawrence Seaway, to the Atlantic Ocean, as well as the Great Lakes to the Mississippi River, via the Illinois River. For decades, O'Hare International Airport has been ranked as one of the world's busiest airports. Illinois has long had a reputation as a bellwether both in social and cultural terms and politics.

Although today the state's largest population center is around Chicago in the northern part of the state, the state's European population grew first in the west, with French Canadians who settled along the Mississippi River, and gave the area the name, Illinois. After the American Revolutionary War established the United States, American settlers began arriving from Kentucky in the 1810s via the Ohio River, and the population grew from south to north. In 1818, Illinois achieved statehood. After construction of the Erie Canal increased traffic and trade through the Great Lakes, Chicago was founded in the 1830s on the banks of the Chicago River, at one of the few natural harbors on southern Lake Michigan.John Deere's invention of the self-scouring steel plow turned Illinois' rich prairie into some of the world's most productive and valuable farmlands, attracting immigrant farmers from Germany and Sweden. Railroads carried immigrants to new homes, as well as being used to ship their commodity crops out to markets.

Ill (France)

The Ill (/ˈɪl/; French: [il]) is a river in Alsace, in north-eastern France. It is a "left-side", or western tributary of the Rhine.

It starts down from its source near the village of Winkel, in the Jura mountains, with a resurgence near Ligsdorf, turns around Ferrette on its east side, and then runs northward through Alsace, flowing parallel to the Rhine. Taking apart the Largue, also coming from the Jura mountains near Illfurth, it receives several tributaries from the west bank Vosges mountains after passing through Altkirch: the Doller in Mulhouse, the Thur near Ensisheim, the Lauch in Colmar, the Fecht in Illhaeusern, the Giessen in Sélestat, the Andlau near Fegersheim, the Ehn near Geispolsheim, the Bruche next to Strasbourg and the Souffel upstream from La Wantzenau before meeting with the Rhine downstream from Gambsheim's lock.

As the Ill nears the city of Mulhouse, most of its flow is diverted into a discharge channel leading to the Doller, protecting the historical center of the town from floods.
