Since we want a word that's not a power of a single letter, our only choice (modulo the letters' names) is to put different letters in the two positions we have control over. Uniqueness follows from the fact that every other position is fixed. The words so obtained are the finite Sturmian words. [2] These words admit many characterisations; [1 ...
In computer science, the two-way string-matching algorithm is a string-searching algorithm, discovered by Maxime Crochemore and Dominique Perrin in 1991. [1] It takes a pattern of size m, called a “needle”, preprocesses it in linear time O(m), producing information that can then be used to search for the needle in any “haystack” string, taking only linear time O(n) with n being the ...
Wordle is a word puzzle that gives players six chances to guess a five-letter word. Originally created by software engineer Josh Wardle and released to the public in 2021, the puzzle was acquired ...
An alphanumeric grid (also known as atlas grid [1]) is a simple coordinate system on a grid in which each cell is identified by a combination of a letter and a number. [ 2 ] An advantage over numeric coordinates such as easting and northing , which use two numbers instead of a number and a letter to refer to a grid cell, is that there can be no ...
A typical five-line staff. In Western musical notation, the staff [1] [2] (UK also stave; [3] plural: staffs or staves), [1] also occasionally referred to as a pentagram, [4] [5] [6] is a set of five horizontal lines and four spaces that each represent a different musical pitch or in the case of a percussion staff, different percussion instruments.
That is, for any two symbols a and b in A that are not the same symbol, either a < b or b < a. The words of A are the finite sequences of symbols from A, including words of length 1 containing a single symbol, words of length 2 with 2 symbols, and so on, even including the empty sequence with no symbols at all. The lexicographical order on the ...
Palindrome: a word or phrase that reads the same in either direction; Pangram: a sentence which uses every letter of the alphabet at least once; Tautogram: a phrase or sentence in which every word starts with the same letter; Caesar shift: moving all the letters in a word or sentence some fixed number of positions down the alphabet; Techniques ...
