122 is a nontotient since there is no integer with exactly 122 coprimes below it. Nor is there an integer with exactly 122 integers with common factors below it, making 122 a noncototient. 122 is a semiprime. φ(122) = φ(σ(122)). [1]
Each digit has a value of 0, 1, or 2. A number can have many skew binary representations. For example, a decimal number 15 can be written as 1000, 201 and 122. Each number can be written uniquely in skew binary canonical form where there is only at most one instance of the digit 2, which must be the least significant nonzero digit. In this case ...
The base-2 numeral system is a positional notation with a radix of 2.Each digit is referred to as a bit, or binary digit.Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used by almost all modern computers and computer-based devices, as a preferred system of use, over various other human techniques of communication, because ...

AOL Search offers a number of search verticals to help you find the information you want quickly and easily. These are located just below the search box at the top of the search results page. The default option is always web search, but you can select another by typing your search term in the box and clicking the name of the category.
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.
Bentley and Yao generalize this variation into one where any number, k, of binary searches are performed during the first stage of the algorithm, giving the k-nested binary search variation. The asymptotic runtime does not change for the variations, running in O ( log i ) {\displaystyle O(\log i)} time, as with the original exponential ...
Online search is the process of interactively searching for and retrieving requested information via a computer from databases that are online. [1] Interactive searches became possible in the 1980s with the advent of faster databases and smart terminals. [ 1 ]
