  2. Maximal munch - Wikipedia

    en.wikipedia.org/wiki/Maximal_munch

    For instance, the lexical syntax of many programming languages requires that tokens be built from the maximum possible number of characters from the input stream. This is done to resolve the problem of inherent ambiguity in commonly used regular expressions such as [a-z]+ (one or more lower-case letters).

  3. 2,147,483,647 - Wikipedia

    en.wikipedia.org/wiki/2,147,483,647

    The number 2,147,483,647 (or hexadecimal 7FFFFFFF 16) is the maximum positive value for a 32-bit signed binary integer in computing. It is therefore the maximum value for variables declared as integers (e.g., as int ) in many programming languages.

  4. Longest words - Wikipedia

    en.wikipedia.org/wiki/Longest_words

    At 51 letters in the Welsh alphabet (the digraphs ll and ch are each collated as single letters) the name can be translated as "St Mary's church in the hollow of the white hazel near to the rapid whirlpool and the church of St Tysilio of the red cave". However, it was artificially contrived in the 1860s as a publicity stunt, to give the station ...

    help.aol.com/articles/aol-mail-limits-on-sending...

    In order to better enforce anti-spam policies, AOL does not disclose the number of recipients or emails that can be sent at one time. If you've received a notification that a limit has been met, you'll need to wait a set amount of time before you can send more emails. Most sending limit notifications inform you of how long you'll have to wait.

  6. Trifid cipher - Wikipedia

    en.wikipedia.org/wiki/Trifid_cipher

    The trifid cipher is a classical cipher invented by Félix Delastelle and described in 1902. [1] Extending the principles of Delastelle's earlier bifid cipher, it combines the techniques of fractionation and transposition to achieve a certain amount of confusion and diffusion: each letter of the ciphertext depends on three letters of the plaintext and up to three letters of the key.

  7. Multigraph (orthography) - Wikipedia

    en.wikipedia.org/wiki/Multigraph_(orthography)

    A multigraph (or pleograph) is a sequence of letters that behaves as a unit and is not the sum of its parts, such as English ch or French eau . The term is infrequently used, as the number of letters is usually specified: Digraph (two letters, as English ch or ea ) Trigraph (three letters, as French tch or eau )

  8. Line length - Wikipedia

    en.wikipedia.org/wiki/Line_length

    The matrix is used by locating the number closest to the previously calculated LCA on the left column of the matrix and then scanning across the columns the number of characters that one would like to set in the text line. Once the number is located, the top row of the selected column will indicate the ideal line length. [13]

  9. Fibonacci word - Wikipedia

    en.wikipedia.org/wiki/Fibonacci_word

    Suppressing the last two letters of a Fibonacci word, or prefixing the complement of the last two letters, creates a palindrome. Example: 01 S 4 = 0101001010 is a palindrome. The palindromic density of the infinite Fibonacci word is thus 1/φ, where φ is the golden ratio : this is the largest possible value for aperiodic words.
