Generics
Generics... you want them. In your solution, they would be relatively easy to apply too. Consider your Node class:
class Node {
Object data;
Node next;
public Node(Object item) {
data = item;
}
public Node(Object item, Node n) {
data = item;
next = n;
}
}

The following JS object displays the time and updates whenever it changes.
If a timestamp URL is provided, the object will use this as the source so that it doesn't completely have to rely on the client's unreliable date. Else, there is unfortunately no other way but to use the client's time. Th...

I think you can simply try this:-
String str = "your input source string";
String strArray[]=str.split(" ");
for(int i=strArray.length()-1;i>=0;i--)
System.out.print(strArray[i]+" ");
Check whether two given arrays are permutation of each others. Does this implementation guaranteed execution of O(n) time ? What is the additional space utilization for this implementation by excluding the original array size, does it O(1)?

I've run into the following sequence of actions many times in iOS dev, and never quite known what the suggested pattern is for implementation:
1) A view controller A creates a new view controller B
2) A sets the frame of B's view
3) B then creates its own subviews, which need to be sized relat...

The Rubberduck project is coming along pretty nicely, and for the next version the parsing strategy is getting yet another revision, and this time around it really feels like it's done right.
Or is it?
The idea is to walk the parse tree once to locate every single declaration.

displays them in the reverse of the order in which they were entered. The minimum and
maximum values that were entered should also be displayed.

My question was tweeted with the automatic Code Review Twitter account.
The tweet in question is using #f#, which isn't valid. It should use #fsharp, like #csharp in this tweet.
I have this simple code :
demo
$float = (float)('33.30'*100);
var_dump($float);
$int = (int)$float;
var_dump($int);
And I get this result :
float(3330)
int(3329)
I have done this ugly fix, but I would like to know if there won't be side effects, and I would really appreciate if someon...
