Google Sheets is a spreadsheet application and part of the free, web-based Google Docs Editors suite offered by Google. Google Sheets is available as a web application; a mobile app for: Android, iOS, and as a desktop application on Google's ChromeOS. The app is compatible with Microsoft Excel file formats. [5]
Example of shuffling five letters using Durstenfeld's in-place version of the Fisher–Yates shuffle The Fisher–Yates shuffle is an algorithm for shuffling a finite sequence . The algorithm takes a list of all the elements of the sequence, and continually determines the next element in the shuffled sequence by randomly drawing an element from ...
Also, programs can be written that pull information from the worksheet, perform some calculations, and report the results back to the worksheet. In the figure, the name sq is user-assigned, and the function sq is introduced using the Visual Basic editor supplied with Excel. Name Manager displays the spreadsheet definitions of named variables x & y.
A simple algorithm to generate a permutation of n items uniformly at random without retries, known as the Fisher–Yates shuffle, is to start with any permutation (for example, the identity permutation), and then go through the positions 0 through n − 2 (we use a convention where the first element has index 0, and the last element has index n − 1), and for each position i swap the element ...
To make worstsort truly pessimal, k may be assigned to the value of a computable increasing function such as : (e.g. f(n) = A(n, n), where A is Ackermann's function). Therefore, to sort a list arbitrarily badly, one would execute worstsort( L , f ) = badsort( L , f (length( L ))) , where length( L ) is the number of elements in L .
An example of a list that proves this point is the list (2,3,4,5,1), which would only need to go through one pass of cocktail sort to become sorted, but if using an ascending bubble sort would take four passes. However one cocktail sort pass should be counted as two bubble sort passes.
Since a (,)-shuffle is completely determined by how its first elements are mapped, the number of (,)-shuffles is (+).. However, the number of distinct riffles is not quite the sum of this formula over all choices of and adding to (which would be ), because the identity permutation can be represented in multiple ways as a (,)-shuffle for different values of and .
For example, there are only countably many sets, so one might think that these should be non-random. However, the halting probability Ω is Δ 2 0 {\displaystyle \Delta _{2}^{0}} and 1-random; it is only after 2-randomness is reached that it is impossible for a random set to be Δ 2 0 {\displaystyle \Delta _{2}^{0}} .
