Exercise: Change Orb Location
-------------------------

### Description

In this series of exercises, you will create functions
to create, modify and examine dictionaries that
represent information about a memory orb. Memory
orbs have three important pieces of information:
The `emotion` that created the memory, the `location`
the memory is stored, and the `data` which is the
information in the memory.

For this exercise, you will create a function that
will change the value of the `location` key in a
dictionary.

### Files

* `orbfunctions.py` : set of functions to work with memory orbs.

### Function Name

`move_orb`

### Parameters

* `orb` : a dictionary
* `new_location` : a string, the new value for `location`

### Action

Changes the value associated with the key `location`.

### Return Value

The modified dictionary, `orb`.

def create_orb(emotion, location, data):
dict = {
"emotion":emotion,
"location":location,
"data":data
}
return dict

def orb_get_emotion(orb):
return orb["emotion"]

def change_orb_emotion(orb, new_emotion):
orb.update({"emotion":new_emotion})
return orb
def orb_get_location(orb):
if orb.get('location'):
return orb.get('location')
else:
return None
  
def move_orb(orb,location):

Find the maximum value and minimum value in milesTracker. Assign the maximum value to maxMiles, and the minimum value to minMiles. Sample output for the given program:

Min miles: -10
Max miles: 40

import java.util.Scanner;

public class ArraysKeyValue {
public static void main (String [] args) {
Scanner scnr = new Scanner(System.in);
final int NUM_ROWS = 2;
final int NUM_COLS = 2;
int [][] milesTracker = new int[NUM_ROWS][NUM_COLS];
int i;
int j;
int maxMiles; // Assign with first element in milesTracker before loop
int minMiles; // Assign with first element in milesTracker before loop

for (i = 0; i < milesTracker.length; i++){
for (j = 0; j < milesTracker[i].length; j++){
milesTracker[i][j] = scnr.nextInt();
}
}

/* Your solution goes here */

System.out.println("Min miles: " + minMiles);
System.out.println("Max miles: " + maxMiles);
}
}

Python Coding:

Working with Conditions and Dictionaries.

1. Create three dictionaries (student_1, student_2, student_3).

2. In each student dictionary have a key-value for first_name, last_name, and an id number (6 digit), and a current_course. The values assigned to each of these keys is your choice.

3. Also each student will have in their dictionary a list for grades. You will need to add 3 grade values into the list.

4. Provide the student with a message about each assignment grade based on the grade value.

For each of the grades for each assignment:

Provide a 90-100 grade message. My example used 'Congratulations'

Provide a 80-89 grade message. My example used 'Good job!'

Provide a 70-79 grade message. My example used 'You passed!'

Provide a 60-69 grade message. My example used 'Bad news, below average'

59 or lower grade message would be 'Failed.'

For each grade:

'You have made a {grade value} on assignment {assignment number}.

5. Print out each student's data as shown in the example output below:

Name: Smith, John   

Id: 646562   

Course: ITSE 1359

Grades: 86, 74, 94

Good job!

You have made a 86 on assignment 1.

You passed!

You have made a 74 on assignment 2.

Congratulations

You have made a 94 on assignment 3.

• Consider the following class definition:

  class circle                                                       class cylinder: public circle
  {                                                                      {
  public:                                                             public:
  void print() const;                                           void print() const;
  void setRadius(double);                                  void setHeight(double);
  void setCenter(double, double);                     double getHeight();
  void getCenter(double&, double&);               double volume();
  double getRadius();                                        double area();
  double area(); circle();                                     cylinder();
  circle(double, double, double);                       cylinder(double, double,
  double, double);
  private:                                                private:
  double xCoordinate;                                       double height;
  double yCoordinate;                         }
  double radius;
  }

  Suppose that you have the declaration:
  cylinder newCylinder;

1. Write the definitions of the member functions of the classes circle and cylinder. Identify the member functions of the class cylinder that overrides the member functions of the class circle.

You are in charge of the computers at a large inner-city library. Most of the people who live in the neighborhood do not have a computer at home. They go to the library when they want to access the Internet. About two-thirds of the people surfing the Web on the library’s computers are adults. You have been requested to install filtering software that would block Websites containing various kinds of material deemed inappropriate for children. You have observed this software in action and know that it also blocks many sites that adults might legitimately want to visit. How should you respond to the request to install filtering software?
