Question
Chapter 11, Problem 11.48P
Interpretation Introduction
Interpretation:
The reason for use of Pb-Sn alloy for soldering should be explained.
Concept Introduction:
Soldering process − By melting and putting a filler into joints, when two items are joined together, then the process is describes as 'Soldering Process'
The adjoined metal has a higher temperature than the filler metal. Melting of work piece is allowed in soldering process, unlike in welding.

(b) Consider two vertices x and y that are simultaneously on the function-call stack at some point during
the execution of depth-first search from vertex s in a digraph. (That is, dfs(x) is called during the
execution of dfs (y), or vice versa. In addition, the initial call is dfs(s).)
Which of the following must be true? For each sub-problem, indicate your answer by circling the appro-
priate response.
I. There is both a directed path from s to x and a directed path from s to y.
Must be true
May be false
II. If there is not a directed path from x to y, then there must be a directed path from y to x.
Must be true
May be false
III. There is both a directed path from x to y and a directed path from y to x.
Must be true
May be false
Consider the following binary tree method for a tree with keys of type Key, which is an object type.
public boolean mystery () {
return mystery (root, null, null);
private boolean mystery (Node x, Key a, Key b) {
}
if (x == null) return true;B
if (a != null && x.key.compareTo(a) = 0) return false;
return mystery (x.left, a,
x.key) &&
mystery (x.right, x.key, b);
(a) In plain English, describe the function of mystery (). (This should be a short, clear answer. Zero
credit for describing the code line by line!)
This question considers binary trees using the following node class. You may not assume that the tree has
any method or additional fields.
class Node {
}
String key;
Node left, right;
Node root%; // the root of the tree
Recall that the height of a node x is the maximum of the number nodes between x and a null link. By
definition, the height of a leaf is 0, and therefore the height of the empty tree is -1.
(a) Implement a method height which returns the height of the tree, starting from the root.
public int height () {

- Suppose C is a class that supports equals, hashCode and compareTo. Objects that are not equals are distinct. Given two arrays a [] and b [], each containing N distinct objects of type C, design two algorithms (with the performance requirements specified below) to determine whether the two arrays contains precisely the same set of values (but possibly in a different order). For each algorithm, give a crisp and concise English description of your algorithm. Your answer will be graded on correctness, efficiency, and clarity. You may use any combination of data structures and algorithms discussed in the course (that is, any standard data structure). You may also describe your own variation. Be specific when identifying any data structure or algorithm that you use ("sorting" and "symbol table" are too vague).
