What's the most effective way to find a number of consecutive elements inside an array?
To give a really basic example, if one had:
var array:Array = [0,1,0,1,1,1,0];
What would be the best way to detect the three consecutive 1s?
I have been playing around with array.some() but it ain't really working out
am developing an application which requires a consecutive searching side to it. Basically, I need a function or a class which takes an array as the parameter, and return the possible 3 consecutive numbers in a 2 dimensional array.For example, if I have this code:
ActionScript Code:
//Global array
var glob:Array=[0,1,2,3,4,5,6,7,8,9];
[code]......

how do you find out in which position a certain value is in an array?
View 9 RepliesI just read the tutorial "Finding Values in an Array". Sure, the code works, but that's only because we are searching arrays the contain a small number of elements. Suppose we have n elements in an array. To search that array for a particular element we may have to do n comparisons. If the array we are searching contains 10 million elements, we have a problem; can you imagine doing "if (this == that)" 10 million times? There's got to be a better way to search the array. Or perhaps we shouldn't use arrays to store the information.
View 9 RepliesI have an array which I am populating as I navigate through the site. Sometimes due to cicumstances apparently out of my control, I end up with two (never more) duplicate values consecutively placed in my array, here is an example:
groceries = ["bananas", "apples", "apples", "oranges"];
I need to run a script at all times that checks to see if this happens, and removes the second duplicate value, as well as it's corresponding key.How can I do this?
does anyone know how to shift all the array elements by one or more without deleting the array itself?
Something like rotating the array:
1,2,3,4,5,6,7,8,9,10
10,1,2,3,4,5,6,7,8,9
9,10,1,2,3,4,5,6,7,8
8,9,10,1,2,3,4,5,6,7
7,8,9,10,1,2,3,4,5,6
I've been trying to move array elements from one array to another using the push method. The problem is that the element pushed should any longer be on the first array where it was taken from. That's where i'm stuck..

Is there a way to write out an array without the that separates the elements in the array?
View 15 RepliesIf I am a subclass of an Array, how do I access an element?
class ArrayOfFoo extends Array
{
public function getFooAt(anIndex : int) : Foo
{
return this[anIndex] as Foo; // <---- looks for an object attribute (named "0", for example)
}
}
I could wrap an array instead of subclassing it, however lacking a universal IArray interface, that is less than useful for standard and custom functions expecting an Array.
This should be a simple one. I am running an IF statement that needs to check the 5th value in a pre-populated array. I'm finding it hard to find the right method of searching the array.
[Code]....
indexOf seems to just return where the value is...but I already know where it is! I just want to know WHAT it is! There will also be values that are exactly the same in other positions in the array. I have to focus in specifically on the 5th value.
I am wondering if Flash has a built in way of finding if a value in an array exists. IndexOf only works with string values, but I couldn't find any function that tries to find a value of any data type in an array.
If there isn't one, I will just end up using this:
Code:
contains = function (array, input) {
for (i=0; i<array.length; i++) {
if (array[i] == input) {
return 1;
}
}
};
I am trying not to use my own functions for things that Flash already has built-in, so I just want to double check with you all in case I missed something
So my array has 5 numbers in it and also the ability to add more to it as the user sees fit.I want to be able to display the max and min number in the array. I made a loop but i am not sure how to make it select the highest or lowest number automatically without me selecting it manually by typing it in.This is my code for determining this:
// Determine Min and Max Markfunction maxandminMark(){var markIndex:int;markIndex=(marks.indexOf(marks));if (markIndex != -1){ for (var i = markIndex; i < marks.length; i++) marks[i] = marks[i+1]; trace(maxandminMark);}}}

How do I find number of all the series (combinations of an array that have at least 3 consecutive values, like [7,8,9]) and have the longest number of values?
from [3,4,1,2,2] it would be 2 - ([1,2,3,4] twice, but ignore [1,2,3]*2 and [2,3,4]*2)
from [9,6,7,5,8] it would be 1 - ([5,6,7,8,9])
[Code]....
this will create an array ($ranks) that will have these values [2:2, 3:1, 4:1, 9:1]
from this I will be able to multiply the values under 2,3 ad4 4 and multiply them by 3, so I would get 2*1*1 * 3
how to find the consecutive values, and ignore ones that aren't (like the 9)
Is there a method or something that will add up all the values in an array and give me a total?
View 2 RepliesI'm trying to find a simple way to solve this problem: I have an array of integers and need to find the highest value that is unique.Specifically, my array holds player scores. Ex: (4,7,6,5,2,7)I need a function that will give me the highest score that it is not tied with another score. So for the example above, it would return 6 (not 7 since there are two 7's)
View 9 Repliesi was looking at the tutorial Finding Values in an Array here and was wondering if i could replace
Code:
dataValues = [10,9,8,7,6,5,4,3,2];
with a string value thats is read from a text box eg,
Code:
dataValues = [myStringValue];
. myStringValue holds
Code:
"1,2,3,4,5,6,7"
and only finds it if i type in the full value, how do i get it to find each value seperatley after each comma? Everytime i try that it doesnt work correctly.
I have an array with about 80 variables in it and everything is working fine, but I can't seem to figure out how to produce a variable name from the array. Example: I sort my array to get the highest value, then I cannot retrieve the actual name of the variable that holds the value.

I looked into "toString" and toLocaleString but they also gives me the number value.

View 3 Repliesam creating a drag and drop activity which utilizes arrays to populate my 'drag' and 'drop' components with their parameters.So far, I am able to get all the drags to work (with a little a few days ago from the boards showthread.php?t=825222) . My problem now is that I need to register which 'drop' is being hit so that I can update the variables for that drop. However, as the drops are in an array, any time I reference that array it uses the information from the third and final drop, even if drop one or two are hit.Here is my code:
PHP Code:
var usingDrop:Number;
//the vars below are specific to each drop and used to be declared in the drop array - i

I am currently working on a tile based game in Flash, so im working with a two dimensional Array containing the data for the map the player can jump around in. The script is already able to find all the groups within the Array. In the following example Array it groups the left ones and the right using the zero tiles to divide them:
[1,1,0,0],
[1,0,0,1],
[1,0,0,1],
[1,0,1,1]
I am already able to get the corners of the groups, but still they are not in the correct order. As well some corners exist twice.
get the corners in the correct order and how to get rid of the doubles?

View 2 RepliesI´m trying to order elements of an array. When the dates come from dynamics text it´s no problem, bad when come from input text the dates are treated like strings and it´s impossible to order correctly, because 15 is considered less than 3. In both cases I can operate correctly whit this dates like numbers.How is possible to order this dates from input text, like numbers?
