发现在AS3数组序列 [英] finding sequences in AS3 array
问题描述
没有任何人有任何想法,该怎么做才能找到序列中的数组数?
例如,我的数组是:
VAR数字:阵列=新阵列(香蕉,香蕉,苹果,香蕉,香蕉);
和我需要找到的是: *多少次有香蕉的序列 *和每个序列的长度。
我做的,为了得到以下结果什么shell: 2,1,2(2香蕉,苹果1个,2个香蕉)
我试着用做while循环,但二想我错过了什么。
一个简单的例子将是非常美联社preciated!
感谢名单
VAR preV:字符串= NULL;
VAR问:INT = 0;
VAR结果:阵列=新的Array();
对于(VAR我:= 0; I< numbers.length ++我){
如果(preV!=号[I]){
如果(Q&0)result.push(q)的;
Q = 1;
preV =号[I]
}
其他++ q;
}
如果(Q&0)result.push(q)的;
这就是假设香蕉等都是字符串(上面可能是笔误?)。这将是简单修改到其它类型的对象
does anyone have any idea what to do in order to find the number of sequences in an array?
for example, my array is:
var numbers:Array = new Array(banana, banana, apple, banana, banana);
and i need to find is: * how many times there is a sequence of "banana" * and the length of each sequence.
what shell i do in order to get the following result: 2,1,2 (2 bananas, 1 apple, 2 bananas)
i tried with do while loop, but i i guess i miss something.
a short example will be very appreciated!
thanx
var prev:String = null;
var q:int = 0;
var result:Array = new Array();
for(var i:int=0; i<numbers.length; ++i){
if(prev!=numbers[i]){
if(q>0) result.push(q);
q=1;
prev=numbers[i];
}
else ++q;
}
if(q>0) result.push(q);
This is, assuming banana, etc. are strings (probably a typo above?). It would be simple to modify to other types of objects
