Chapter 18, Problem 3FTE

Explanation of Solution

Given code:

//implement the "Set" interface

Set <String> nameSet = new HashSet<>(); //Line 1

//add the values into the "Set"

nameSet.add("Chris"); //Line 2

nameSet.add("Kenny"); //Line 3

//declare the "ListIterator"

ListIterator it = nameSet.listIterator();//Line 4

Error in the code:

Error #1:

The error is in “Line 4”. The user can’t get a “ListIterator” from the object, which implements the “Set” interface...

a) first player is the minimizing player. What move should be chosen?b) What nodes would not need to be examined using the alpha-beta pruning procedure?
Consider the problem of finding a path in the grid shown below from the position S to theposition G. The agent can move on the grid horizontally and vertically, one square at atime (each step has a cost of one). No step may be made into a forbidden crossed area. Inthe case of ties, break it using up, left, right, and down.(a) Draw the search tree in a greedy search. Manhattan distance should be used as theheuristic function. That is, h(n) for any node n is the Manhattan distance from nto G. The Manhattan distance between two points is the distance in the x-directionplus the distance in the y-direction. It corresponds to the distance traveled along citystreets arranged in a grid. For example, the Manhattan distance between G and S is4. What is the path that is found by the greedy search?(b) Draw the search tree in an A∗search. Manhattan distance should be used as the
