Can you guys help me with the algorithm to do these things? I have preorder, inorder, and postorder implemented, and I am given the hint to traverse the tree with one of these orders. I am using dotty to label (or "visit") the nodes.

Depth is the number of edges from the root to the bottom leaf, so everytime I move, I add +1 to the depth? Something like that?

No idea about the algorithm for descendants. They are asking about the number of nodes a specific node has under itself.

These are normal trees btw.

B- trees, B+ trees difference

as seen on Stack Overflow - Search for 'Stack Overflow'
In a B- tree you can store both keys and data in the internal/leaf nodes. But in a B+ tree you have to store the data in the leaf nodes only. Is there any advantage of doing the above in a B+ tree? Why not use B- trees instead of B+ trees everywhere? As intuitively they seem much faster. I mean why… >>> More

I sometimes disable depth buffer writing via glDepthMask(GL_FALSE) during the alpha rendering of a frame. That works perfectly fine on some GPUs (like the Motorola Droid's PowerVR), but on the HTC EVO with the Adreno GPU for example, I end up with the frame buffer being complete garbage (I see traces… >>> More
