HackerRank's programming challenges can be solved in a variety of programming languages (including Java, C++, PHP, Python, SQL, and JavaScript) and span multiple computer science domains. [ 2 ] HackerRank categorizes most of their programming challenges into a number of core computer science domains, [ 3 ] including database management ...
An anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once. [1] For example, the word anagram itself can be rearranged into the phrase "nag a ram"; which is an Easter egg suggestion in Google after searching for the word "anagram". [2]
The idea of a trie for representing a set of strings was first abstractly described by Axel Thue in 1912. [2] [3] Tries were first described in a computer context by René de la Briandais in 1959.
The first such anagram dictionary was The Crossword Anagram Dictionary by R.J. Edwards [1] In the other kind of anagram dictionary, words are categorized into equivalence classes that consist of words with the same number of each kind of letter. Thus words will only appear when other words can be made from the same letters.
A Lychrel number is a natural number that cannot form a palindrome through the iterative process of repeatedly reversing its digits and adding the resulting numbers. This process is sometimes called the 196-algorithm, after the most famous number associated with the process.
In computational linguistics and computer science, edit distance is a string metric, i.e. a way of quantifying how dissimilar two strings (e.g., words) are to one another, that is measured by counting the minimum number of operations required to transform one string into the other.
The poem "Anagram" from the 1633 edition of George Herbert's The Temple, connecting the words Mary and army. Anagrammatic poetry is poetry with the constrained form that either each line or each verse is an anagram of all other lines or verses in the poem. A poet that specializes in anagrams is an anagrammarian. [1]
Palindromes and Anagrams was a modest success when first published, selling over 13,000 copies by 1979. [2] It was favourably reviewed in Word Ways, the journal of recreational linguistics which Bergerson formerly edited; fellow ex-editor Borgmann wrote that the book succeeds in "impart[ing] to palindromes and anagrams a status, a dignity, and a future they have not heretofore possessed", and ...
