Give two or more good reasons to have a catch (exception_type) clause rather than a catch (exception_type ex). (Note the absence of the exception parameter name behind the typename in t he first case. This appears to male it impossible to access any exception information inside the catch block.) What is the difference between a binary tree and a general tree in which each node has at most two branches? Describe or implement a method that inserts values from a sorted list into a binary search tree in such a way as to maintain balance yet require no explicit balancing. Explain the operation of treesort in no more than 19 words. If a hash function assigns 57 keys to random positions in a hash table of size 365, approximately how likely is it that there will be no collisions? C++ is an octopus made by mailing extra legs onto a _______.

Explanation / Answer

Let's start with graphs. A graph is a collection of nodes and edges. If you drew a bunch of dots on paper and drew lines between them arbitrarily, you'd have drawn a graph. A directed acyclic graph is a graph with some restrictions: all the edges are directed (point from one node to another, but not both ways) and the edges don't form cycles (you can't go around in circles forever). A tree, in turn, is a directed acyclic graph with the condition that every node is accessible from a single root. This means that every node has a "parent" node and 0 or more "child" nodes, except for the root node which has no parent. A binary tree is a tree with one more restriction: no node may have more than 2 children. More specific than binary trees are balanced binary trees, and more specific than that, heaps. A binary tree can be empty ..whereas the general tree cannot be empty:)
