Hi,
When I used previous versions of Eclipse (e.g. Ganymede/Europa) if I had edited a file and then attempted a build Eclipse would prompt me to save first.
Since I updated to Galileo (Build id: 20090920-1017 & just checked for updates) when I build I'm not prompted to save first. Perhaps the dialog had a checkbox for "don't tell me again"…
Consider the following code:
public int heightOfBinaryTree(Node node)
{
if (node == null)
{
return 0;
}
else
{
return 1 +
Math.max(heightOfBinaryTree(node.left),
heightOfBinaryTree(node.right));
}
}
I want to know the logical reasoning…

Looking for good source code either in C or C++ or Python to understand how a hash function is implemented and also how a hash table is implemented using it.
Very good material on how hash fn and hash table implementation works.
Thanks in advance.

If the user do ctrl+v in a textbox, InputManager correctly notices it. However, if the paste is done from the context menu of the textbox, the InputManager never fires the…

I started writing one using reflection but it turned out…
