Consider the following class declarations. public class Dog
{
private String name;
public Dog()
{
name = "NoName";
}
}
public class Poodle extends Dog
{
private String size;
public Poodle(String s)
{

size = s;
}
}

The following statement appears in a method in another class.
Poodle myDog = new Poodle("toy");
Which of the following best describes the result of executing the statement?

a. The Poodle variable myDog is instantiated as a Poodle. The instance variable size is initialized to "toy". The instance variable name is not assiged a value.
b. The Poodle variable myDog is instantiated as a Poodle. The instance variable size is initialized to "toy". An implicit call to the no-argument Dog constructor is made, initializing the instance variable name to "NoName".
c. The Poodle variable myDog is instantiated as a Poodle. The instance variable size is initialized to "toy". An implicit call to the no-argument Dog constructor is made, initializing the instance variable name to "toy".
d. A runtime error occurs because super is not used to call the no-argument Dog constructor.
e. A runtime error occurs because there is no one-argument Dog constructor.

The idea that, for each pair of devices v and w, there’s a strict dichotomy between being “in range” or “out of range” is a simplified abstraction. more accurately, there’s a power decay function f (·) that specifies, for a pair of devices at distance δ, the signal strength f(δ) that they’ll be able to achieve on their wireless connection. (we’ll assume that f (δ) decreases with increasing δ.) we might want to build this into our notion of back-up sets as follows: among the k devices in the back-up set of v, there should be at least one that can be reached with very high signal strength, at least one other that can be reached with moderately high signal strength, and so forth. more concretely, we have values p1 ≥ p2 ≥ . . ≥ pk, so that if the back-up set for v consists of devices at distances d1≤d2≤≤dk,thenweshouldhavef(dj)≥pj foreachj. give an algorithm that determines whether it is possible to choose a back-up set for each device subject to this more detailed condition, still requiring that no device should appear in the back-up set of more than b other devices. again, the algorithm should output the back-up sets themselves, provided they can be found.\
