A string-searching algorithm, sometimes called string-matching algorithm, is an algorithm that searches a body of text for portions that match by pattern. A basic example of string searching is when the pattern and the searched text are arrays of elements of an alphabet ( finite set ) Σ.
The English Wikipedia has several templates and Lua modules which can format or manipulate strings.In this context a "string" is any piece of text forming part of a page. This help page covers a few useful techniques; look in the navbox below for the full catalogue of templa
The figure shows the Visual Basic code for a subroutine that reads each member of the named column variable x, calculates its square, and writes this value into the corresponding element of named column variable y. The y column contains no formula because its values are calculated in the subroutine, not on the spreadsheet, and simply are ...
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
A Markov Chain with 4 states for the String Generation problem. The first state represents the empty string, the second state the string "H", the third state the string "HT", and the fourth state the string "HTH". Although in reality, the coin flips cease after the string "HTH" is generated, the perspective of the absorbing Markov chain is that ...
This list of chemical elements named after places includes elements named both directly and indirectly for places. 41 of the 118 chemical elements have names associated with, or specifically named for, places around the world or among astronomical objects.
Tennessine and Californium were named after American states Tennessee and California respectively. Dubnium and Moscovium were named after Russia's Dubna [23] and Moscow cities. Several places in Scandinavia have elements named after them. Yttrium, terbium, erbium, and ytterbium are all named for the Swedish village of Ytterby, where their ores ...
This list of chemical elements named after people includes elements named for people both directly and indirectly. Of the 118 elements, 19 are connected with the names of 20 people. 15 elements were named to honor 16 scientists (as curium honours both Marie and Pierre Curie). Four others have indirect connection to the names of non-scientists. [1]
