How to shuffle the elements in the pairs? The program below, generate all possible pairs and later shuffle the pairs. e.g. possible pairs before shuffle is ab,ac,ae,af..etc shuffled to ac,ae,af,ab...etc How to make it not only shuffled in pairs but within the elements in the pair itself? e.g. instead of ab, ac, how can I make ba, ac ? ...
I'm interested making an implementation of the 14-15 puzzle: I'm creating an array with the values 0 - 15 in increasing order: S = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 } Now, what I want to do is shuffle them to create a new instance of the puzzle. However, I know that if I create a board with an "odd permutation" ...
i want after i shuffle a list of images to get all the alt="" value in one array! but i get always the save value!why? $('ul').shuffle(); //this will shuffle the list var a = {}; $("ul img").each(function() { a[this.alt] = $(this).attr("alt"); }); $.operation(a, shuffle); ...
Hi, I'm trying to do something that is fairly simple, but my code looks terrible and I am certain there is a better way to do things in javascript. I am new to javascript, and am trying to improve my coding. This just feels very messy. All I want to do is to randomly change the order some words on a web page. In python, the code would ...
Hello people. I'd like to know if the absence of element ordering of the Python's built-in set structure is "random enough". For instance, taking the iterator of a set, can it be considered a shuffled view of its elements? (If it matters, I'm running Python 2.6.5 on a Windows host.) ...
What will prompt one to use this method? Update : I see the point now. I like the reason of Uri "Shuffling is not a trivial algorithm". That is quite true. ...
I have a list which I shuffle with the Python built in shuffle function (random.shuffle) However, the Python reference states: Note that for even rather small len(x), the total number of permutations of x is larger than the period of most random number generators; this implies that most permutations of a long sequence can never be g...
Hello, Like the str_shuffle() function in PHP, is there a function similar in shuffling the string in javascript ? Please help ! ...
I want to write a function which randomizes the order of a sequence of alphabetic characters. For example, the sequence: A B C D E F G . . . ...might be changed to: Z L T A P ... ...which, if passed to the same function again could result in: H R E I C .... Any suggestions? ...
I do dump the value of RUBY_VERSION => 1.8.7 every time, the value of [1,3,5].shuffle is also [1,3,5] i have to add a srand(Time.now.to_i) or srand() in front of it to make it random... I thought srand is automatically called? but maybe not in a .cgi environment? if i use irb, and look at [1,3,5].shuffle, and exit, and re-enter irb, e...
Following is from python website, about random.shuffle(x[, random]) Shuffle the sequence x in place. The optional argument random is a 0-argument function returning a random float in [0.0, 1.0); by default, this is the function random(). Note that for even rather small len(x), the total number of permutations of x is large...
I already know there's answers for this kind of thing, but I don't really know how to implement them in my code. Also, I would like to refrain from using any more functions unless neccessary. Here's my code: int main() { unsigned seed; seed = 1; srand(seed); std::string starFox[8]; int x[8]; starFox[0] = "Do a barrel roll!"; sta...
Hey Y'all, I was just wondering if there's a way (using ASP.NET C#) to "shuffle" up the contents of a string, but still be able to click another button and "UNshuffle" it back to its original content withOUT saving the original content? Thank you :) Example: "This is not shuffled." "isuo .tffsnl iTh shed" ...And then I click the "U...
I have a set of quiz game questions in a sql database (javascript and sqlite actually). The questions all have a difficulty level from 1 to 5, 5 being hardest. Here is a simplified visualization of the data... +---------+--------------+ | id | difficulty | +---------+--------------+ | 1 | 1 | | 2 ...
Hi all - Here's a C implementation of Fisher-Yates that I want to use in a deck-shuffling routine. Am I doing this correctly (n = length of array)? Note: The do-while loop attempts to correct for the modulo bias (see here). It adds a bit of overhead to the procedure and could be eliminated if you don't care about the low-bit bias. voi...
What's a good algorithm to shuffle the lines in a file without reading the whole file in advance? I guess it would look something like this: Start reading the file line by line from the beginning, storing the line at each point and decide if you want to print one of the lines stored so far (and then remove from storage) or do nothing an...
What is the easiest way to return an array in random order in Ruby? Anything that is nice and short that can be used in an IRB session like [1,2,3,4,5].random() # or random_sort([1,2,3,4,5]) ...
How would I code a reversible shuffle algorithm in C# which uses a key to shuffle and can be reversed to the original state? For instance, I have a string: "Hello world", how can I shuffle it so that later I could be able to reverse the shuffled string back to "Hello world". ...
I have written this function which shuffles the contents of a NSString, and it seems to work, but every now and then it crashes. This may be a roundabout way, but I put the characters into an array, swap the elements in the array randomly, and then turn the array back into a string. I'm not sure what I am doing that is unsafe which make...
