For example, a digital door lock with a 4-digit code (each digit having 10 possibilities, from 0 to 9) would have B (10, 4) solutions, with length 10 000. Therefore, only at most 10 000 + 3 = 10 003 (as the solutions are cyclic) presses are needed to open the lock, whereas trying all codes separately would require 4 × 10 000 = 40 000 presses.
For instance, the combination Alt+ 1 6 3 would result in ú (Latin letter u with acute accent) which is at 163 in the OEM code page of CP437 or CP850, while Alt+ 0 1 6 3 yields the character £ (symbol for the pound sterling) which is at 163 in CP1252. The numbers 0 –31 and 127 are control characters in the Windows code pages. Typing these ...
The list of all single-letter-single-digit combinations contains 520 elements of the form [ [ { {letter}} { {digit}}]] and [ [ { {letter}}- { {digit}}]]. In general, any abbreviation expansion page is located at the shorter link. Once the abbreviation page has been created, the hyphen link should { { R from abbreviation }} to the other page.
A Gray code absolute rotary encoder with 13 tracks. Housing, interrupter disk, and light source are in the top; sensing element and support components are in the bottom. Gray codes are used in linear and rotary position encoders ( absolute encoders and quadrature encoders) in preference to weighted binary encoding.
Unicode characters can then be entered by holding down Alt, and typing + on the numeric keypad, followed by the hexadecimal code, and then releasing Alt. This may not work for 5-digit hexadecimal codes like U+1F937. Some versions of Windows may require the digits 0-9 to be typed on the numeric keypad or require NumLock to be on. [citation needed]
The main purpose of the combinatorial number system is to provide a representation, each by a single number, of all possible k -combinations of a set S of n elements. Choosing, for any n, {0, 1, ..., n − 1 } as such a set, it can be arranged that the representation of a given k -combination C is independent of the value of n (although n must ...
The list of all single-digit-single-letter combinations contains 1040 different combinations of the form [ [ { {digit}} { {letter}}]] and [ [ { {digit}}- { {letter}}]]. In general, any abbreviation expansion page is located at the shorter link. Once the abbreviation page has been created, the hyphen link should { { R from abbreviation }} to the ...
This is a list of some binary codes that are (or have been) used to represent text as a sequence of binary digits "0" and "1". Fixed-width binary codes use a set number of bits to represent each character in the text, while in variable-width binary codes, the number of bits may vary from character to character.
