In theoretical computer science, the closest string is an NP-hard computational problem, [1] which tries to find the geometrical center of a set of input strings. To understand the word "center", it is necessary to define a distance between two strings. Usually, this problem is studied with the Hamming distance in mind.
An English language pangram being used to demonstrate the Bitstream Vera Sans typeface. The best-known English pangram is "The quick brown fox jumps over the lazy dog". [1]It has been used since at least the late 19th century [1] and was used by Western Union to test Telex/TWX data communication equipment for accuracy and reliability. [2]
Henry tells John and Sherlock about the words "liberty" and "in" in his dreams. Sherlock, John, and Henry then visit the hollow in the hope of finding the hound. On the way, John hangs back to observe what seems to be Morse code signals but these prove to be unrelated to the case. When he catches up to Sherlock and Henry, Henry says that he has ...
Their enterprise-side product, HackerRank for Work, is a subscription service that aims to help companies source, screen (CodePair), and hire engineers and other technical employees. [12] The product is intended to allow technical recruiters to use programming challenges to test candidates on their specific programming skills and better ...
Techniques such as alphabet reduction may alleviate the high space complexity by reinterpreting the original string as a long string over a smaller alphabet i.e. a string of n bytes can alternatively be regarded as a string of 2n four-bit units and stored in a trie with sixteen pointers per node. However, lookups need to visit twice as many ...
The luggage tag reveals her name to have been Jennifer Wilson and gives her phone number. With this information Sherlock learns that Rachel was the name of Wilson's deceased daughter. Meanwhile, John is compelled to meet a man who claims to be Sherlock's "arch-enemy". The man offers him money to spy on Sherlock, but John refuses.
A fuzzy Mediawiki search for "angry emoticon" has as a suggested result "andré emotions" In computer science, approximate string matching (often colloquially referred to as fuzzy string searching) is the technique of finding strings that match a pattern approximately (rather than exactly).
This means that, among other things, a pattern can match strings of repeated words like "papa" or "WikiWiki", called squares in formal language theory. The pattern for these strings is (.+)\1 . The language of squares is not regular, nor is it context-free , due to the pumping lemma .
