Tyrone Shoelaces has invested a huge amount of money into the stock market and doesnât trust just anyone to give him buying and selling information. Before he will buy a certain stock, he must get input from three sources. His first source is Pain Webster, a famous stock broker. His second source is Meg A. Cash, a self-made millionaire in the stock market, and his third source is Madame LaZora, world-famous psychic. After several months of receiving advice from all three, he has come to the following conclusions:

a) Buy if Pain and Meg both say yes and the psychic says no.

b) Buy if the psychic says yes.

c) Donât buy otherwise.

Construct a truth table and find the minimized Boolean function to implement the logic telling Tyrone when to buy.

Solution :

The truth table is :

Pain      Meg       Psych     Buy

   [tex]$0$[/tex]           [tex]$0$[/tex]                [tex]$0$[/tex]            [tex]$0$[/tex]

   [tex]$0$[/tex]           [tex]$0$[/tex]                [tex]$1$[/tex]            [tex]$1$[/tex]

   [tex]$0$[/tex]           [tex]$1$[/tex]                [tex]$0$[/tex]           [tex]$0$[/tex]

   [tex]$0$[/tex]           [tex]$1$[/tex]                 [tex]$1$[/tex]             [tex]$1$[/tex]

   [tex]$1$[/tex]            [tex]$0$[/tex]               [tex]$0$[/tex]            [tex]$0$[/tex]

   [tex]$1$[/tex]            [tex]$0$[/tex]               [tex]$1$[/tex]             [tex]$1$[/tex]

   [tex]$1$[/tex]            [tex]$1$[/tex]                [tex]$0$[/tex]            [tex]$1$[/tex]

   [tex]$1$[/tex]           [tex]$1$[/tex]                  [tex]$1$[/tex]              [tex]$1$[/tex]

The Boolean function :

[tex]$\text{F(Pain, \ Meg, \ Psych)}$[/tex] = [tex]$\overline {\text{PainMeg}}\text{Psych}+\overline{\text{Pain}}\text{MegPsych}+\text{Pain}\overline{\text{Meg}}\text{Psych}+\text{PainMeg}\overline{\text{Psych}}$[/tex][tex]$+\text{PainMegPsych}$[/tex]

                              Meg and Psych

                           [tex]$00$[/tex]     01     [tex]$11$[/tex]       10

  Pain         0                 1        1

                   [tex]$1$[/tex]                 [tex]$1$[/tex]        1        [tex]$1$[/tex]

Therefore,

[tex]$\text{F(Pain, \ Meg, \ Psych)}$[/tex]  = Psych + PainMeg

A video game character can face toward one of four directions: north, south, east, and west. Each direction is stored in memory as a sequence of four bits. A new version of the game is created in which the character can face toward one of eight directions, adding northwest, northeast, southwest, and southeast to the original four possibilities. Which of the following statements is true about how the eight directions must be stored in memory?
A. Four bits are not enough to store the eight directions. Five bits are needed for the new version of the game.
B. Four bits are enough to store the eight directions
C. Four bits are not enough to store the eight directions. Sodeen bits are needed for the new version of the game.
D. Four bits are not enough to store the eight directions. Eight bits are needed for the new version of the game.

You are given an array of arrays a. Your task is to group the arrays a[i] by their mean values, so that arrays with equal mean values are in the same group, and arrays with different mean values are in different groups. Each group should contain a set of indices (i, j, etc), such that the corresponding arrays (a[i], a[j], etc) all have the same mean. Return the set of groups as an array of arrays, where the indices within each group are sorted in ascending order, and the groups are sorted in ascending order of their minimum element.

Example

For
a = [[3, 3, 4, 2],
[4, 4],
[4, 0, 3, 3],
[2, 3],
[3, 3, 3]]
the output should be

meanGroups(a) = [[0, 4],

[1],

[2, 3]]

mean(a[0]) = (3 + 3 + 4 + 2) / 4 = 3;
mean(a[1]) = (4 + 4) / 2 = 4;
mean(a[2]) = (4 + 0 + 3 + 3) / 4 = 2.5;
mean(a[3]) = (2 + 3) / 2 = 2.5;
mean(a[4]) = (3 + 3 + 3) / 3 = 3.
There are three groups of means: those with mean 2.5, 3, and 4. And they form the following groups:

Arrays with indices 0and 4 form a group with mean 3;
Array with index 1 forms a group with mean 4;
Arrays with indices 2and 3 form a group with mean 2.5.
Note that neither

meanGroups(a) = [[0, 4],

[2, 3],

[1]]

nor

meanGroups(a) = [[0, 4],

[1],

[3, 2]]

will be considered as a correct answer:

In the first case, the minimal element in the array at index 2 is 1, and it is less then the minimal element in the array at index 1, which is 2.
In the second case, the array at index 2 is not sorted in ascending order.
For
a = [[-5, 2, 3],
[0, 0],
[0],
[-100, 100]]
the output should be

meanGroups(a) = [[0, 1, 2, 3]]

The mean values of all of the arrays are 0, so all of them are in the same group.

What you need to know In this program, a roll string is a number, followed by a lowercase "d", followed by another number. The first number is the number of dice to roll. The second number is the number of sides on each die. For example, 1d6 means there is one die with six sides. The total output of the roll is a random whole number between one and six, inclusive. 2d8 means there are two dice, each with eight sides. The total output of the roll is a random whole number between two and 16, inclusive. Since we are using a computer, we can have an input like 500d1000 (meaning a 1000-sided die, rolled 500 times) which would not be possible in real life.
Function: get_roll(rollstring)
This function takes an input parameter as a string that looks like "1d3", "3d5", etc. The function should return an integer simulating those dice rolls. In the case of "3d5", for example, the function will generate a random number between one and five, three times, and return the total (sum) as an integer. This function should return the value back to get_damage().
Function: get_damage(attack, defense)
This function gets the value of damage based on roll strings. Player 1 (the first roll) is always on attack; Player 2 (the second roll) is always on defense. If the defense roll is greater than the attack roll, return 0. Otherwise, return attack minus defense, as an integer. This function should call get_roll() twice, once for each Player. This function should return the value back to main_main().
Function: main_menu()
In this function, ask the user how many rounds they want to play. Next, ask the user to input Player 1 and Player 2’s dice for roll one, roll two, etc., up to the number of rolls they entered. The rolls for each round must be entered on one line with no spaces. This function should call get_damage() for each round.

1. Add the following method to the Point class:
public double distance(Point other)
Returns the distance between the current Point object and the given other Point object. The distance between two points is equal to the square root of the sum of the squares of the differences of their x- and y-coordinates. In other words, the distance between two points (x1, y1) and (x2, y2) can be expressed as the square root of (x2 - x1)2 + (y2 - y1)2. Two points with the same (x, y) coordinates should return a distance of 0.0.
public class Point {
int x;
int y;

}
2. Create a class called Name that represents a person's name. The class should have fields named firstName representing the person's first name, lastName representing their last name, and middleInitial representing their middle initial (a single character). Your class should contain only fields for now.
3. Add two new methods to the Name class:
public String getNormalOrder()
Returns the person's name in normal order, with the first name followed by the middle initial and last name. For example, if the first name is "John", the middle initial is 'Q', and the last name is "Public", this method returns "John Q. Public".
public String getReverseOrder()
Returns the person's name in reverse order, with the last name preceding the first name and middle initial. For example, if the first name is "John", the middle initial is 'Q', and the last name is "Public", this method returns "Public, John Q.".
4. Add the following method to the Point class:
public int quadrant()
Returns which quadrant of the x/y plane this Point object falls in. Quadrant 1 contains all points whose x and y values are both positive. Quadrant 2 contains all points with negative x but positive y. Quadrant 3 contains all points with negative x and y values. Quadrant 4 contains all points with positive x but negative y. If the point lies directly on the x and/or y axis, return 0.
public class Point {
private int x;
private int y;

In the QuickSort algorithm, the partition method we developed in class chose the start position for the pivot. We saw that this leads to worst case performance, O(n2), when the list is initially sorted. Try to improve your QuickSort by choosing the value at the middle, instead of the value at the start, for the pivot. Test your solution with the Driver you used for homework. Upload the output produced by the Driver, and your modified QuickSort source file.

EXTRA CREDIT - 1 point! Scenario: A small business has implemented the best way to handle the few Service Accounts they have in their AD: They use a random password generator to set Service Account passwords, have 1 Service Account per service, and policies are set so that the accounts do not expire. The current passwords are not even stored anywhere. The company rigorously documents this setup, and diligently deprovisions accounts when services configurations change. The company has also implemented Account Monitoring, and know when any of the Service Accounts is being attempted to be used without the correct password, indicating an attack attempt. Due to the security sensitivity of the data accessible via the Service Accounts, any attack attempts will cause the service account to be disabled and IT staff alerted. Finally, the company has implemented a script that can be used to update the existing passwords -- resetting them via the only account delegated this authority: the Enterprise Root account. To ensure none of the IT staff can use the Enterprise Root account to reset a Service Account without consent, the password for the Enterprise Root account is only known to the company's CIO (Chief Information Officer), and is not stored anywhere. Identify (1) one major problem that you can see with this setup, and describe why this is a problem. There are multiple correct answers possible for this EXTRA CREDIT question.
