First and foremost, a word is basically a sequence of symbols, or letters, in a finite set. [1] One of these sets is known by the general public as the alphabet. For example, the word "encyclopedia" is a sequence of symbols in the English alphabet, a finite set of twenty-six letters. Since a word can be described as a sequence, other basic ...

R is a programming language for statistical computing and data visualization.It has been adopted in the fields of data mining, bioinformatics and data analysis. [9]The core R language is augmented by a large number of extension packages, containing reusable code, documentation, and sample data.
The California Job Case was a compartmentalized box for printing in the 19th century, sizes corresponding to the commonality of letters. The frequency of letters in text has been studied for use in cryptanalysis, and frequency analysis in particular, dating back to the Arab mathematician al-Kindi (c. AD 801–873 ), who formally developed the method (the ciphers breakable by this technique go ...
In combinatorial mathematics, a de Bruijn sequence of order n on a size-k alphabet A is a cyclic sequence in which every possible length-n string on A occurs exactly once as a substring (i.e., as a contiguous subsequence). Such a sequence is denoted by B(k, n) and has length k n, which is also the number of distinct strings of length n on A.
This can be proved by constructing a square-free word without the two-letter combination ab. As a result, bcba cbca cbaca is the longest square-free word without the combination ab and its length is equal to 13. Note that over a more than three-letter alphabet there are square-free words of any length without an arbitrary two-letter combination.
In Pinyin alphabetical order, where words have the same basic letters in pinyin and differ only in modifying diacritics, the unmodified letter comes before the modified letter. For example, e comes before ê (額 ( è ) before 欸 ( ê̄ )), and u comes before and ü (路 ( lù ) before 驢 ( lǘ ) and 努 ( nǔ ) before 女 ( nǚ )).
Linguistic sequence complexity (LC) is a measure of the 'vocabulary richness' of a genetic text in gene sequences. [1] When a nucleotide sequence is written as text using a four-letter alphabet, the repetitiveness of the text, that is, the repetition of its N-grams (words), can be calculated and serves as a measure of sequence complexity.
