File has a format Name and number, the number represents power. The name and the (integer) power are separated by some amount of space. Importantly, any line that begins with a hash '#' are comments and they need to be ingored. Write a program that reads from that file, and prints out only the name of the hero with the strongest power. That name should be capitalized (not uppercase, but capitalized, as in 'Galadriel')

Here is the heroes.txt

# DC heroes
# format: "name" "power"

What i have so far:

fn = open('heroes.txt')
count = 0

for z in fn:
line = z.strip()
  
if not '#' in line:
print(line.capitalize())
continue
po1 = line.find()
print(po1)

Consider a 10Mbps Ethernet network consisting of 20 nodes interconnected by a bus topology with a single bridge placed in the approximate center of the network resulting in an equal umber of nodes on each side of the bridge.

1. Briefly explain why collisions can/cannot occur.

2. If two pairs of nodes attempted to communicate at the same time, discuss the throughput they can achieve.

Given a Syntax Directed Translation as follows.

Question

Create an annotated parse tree for the following statements

1. a. (3+4) * (5+6)n

Shapes2D

Write the following four classes to practice using an abstract class and polymorphism. Submit all four classes.

Shape2D class

For this class, include just an abstract method name get2DArea() that returns a double.

Rectangle2D class

Make this class inherit from the Shape2D class. Have it store a length and a width as fields. Provide a constructor that takes two double arguments and uses them to set the fields. Note, the area of a rectangle is the length times the width.

Rectangle2D class

Also make this class inherit from the Shape2D class. Have it store a radius as a field. Provide a constructor that takes a double argument and uses it to set the field. Note, the area of a circle is PI times it's radius times it's radius.

Shape2DDriver class

Have this class provide a method named displayName() that takes an object from just any of the above three classes (you can't use an Object type parameter). Have the method display the area of the object, rounded to one decimal place.

Two computers have 7-stage fetch-execute cycles where branches are determined in stage 4. One computer is not pipelined, and the other is pipelined. Assuming that tp = 1, answer the following questions when running a program with 50,000 instructions where 1,000 of the instructions are conditional branches and each branch, if taken, skips over 10 instructions.a.How much faster is the pipelined machine over the non-pipelined machine assuming that no branches are taken.b.How much faster is the pipelined machine over the non-pipelined machine assuming that all branches are taken.c.Bonus question: How many branches would the program have to have assuming every branch is taken (and every branch skips over 10 instructions) for the non-pipelined machine to execute the program in the same time as the pipelined machine?

There are 4 processes with different arrival time and service time.

a. Use FCFS, RR(4), SPN, SRT, and HRRN to schedule them. Calculate the waiting time and turnaround time for each process and the average turnaround time for each algorithm.

b. Compare all the 5 algorithms. Considering the overhead time for each scheduling takes 1 time unit, which is the best? If the overhead takes 4 time units, which is the best?

Use R programming Language

Q1.

(a)Write a function called lowerTrim that takes 2 arguments: x and trimBelow. This function takes the average of those values in x that are greater than the trimBelow. Make x a required argument and supply a default value for trimBelow of negative infinity.

First create some variable to be used for testing later.

x = 1:5
y = letters
z = list(a = 1:5, b = 1:10)

Now test your function with the following

lowerTrim(x)
lowerTrim(-10:5, trimBelow = 0)
lowerTrim(-10:5, -2)
lowerTrim(x = -10:5, trimBelow = Inf)

The return values should be: 3, 3, 2, and NaN, respectively

(b). Extend your function so that it takes a third parameter, which allows the caller to use a function other than mean() when calculating the lowerTrim. Call this argument sumFunc and give it a default value so that it operates like the original lowerTrim function. Call this revised function lowerTrim2

Check your function with the following calls:

lowerTrim2(-10:20, trimBelow = -5, median)
lowerTrim2(-10:20, trimBelow = 0, sumFunc = summary)

The return values should be 8 and the summary values of 1, 5.75 10.5, 10.5, 15.2, and 20.

(c) Modify your function to take in any argument through the ... argument and pass these arguments. Call this new function lowerTrim3.

And test your code with

lowerTrim3(x, sumFunc = sd)
lowerTrim3(-10:20, trimBelow = 0, sumFunc = quantile,
           probs = 0.99)
lowerTrim3(-10:20, trimBelow = 0, trim = 0.1)

The results should be 1.58, 19.8, and 10.5.

For Problems 1–4, using the STORES Database, formulate SQL queries, Hand in a listing of each query and its output.

1. (10 Points) For each customer, list each stock item ordered, the manufacturer, the quantity ordered, and the total price paid. Include the following columns in the order given below:

From Customer Table:              Company

From Stock Table:                      Description

From the Manufact Table:        Manu_Name

From the Items Table:                                Quantity, Total Price

Order the output by Company and Description.

2. (10 Points) List all orders with a shipping date between December 25, 1999 and January 5, 2000. List the Order Number, Order Date, Customer company name, and Shipping Date. Order by Customer Company Name and Order Number.

4. (10 Points) List all customers who are ordering equipment whose description begins with ‘tennis’ or ‘volleyball’. List the Customer number, Stock number, and Description. Do not repeat any rows.

5. (15 Points) Use the following SQL CREATE commands to CREATE the following tables in your

User ID:

                                CREATE TABLE Professor

                                (Prof_ID                NUMBER(3) Constraint pk_Professor Primary Key,

                                Prof_Lname         VARCHAR2(15)                 NOT NULL,

                                Prof_Hiredate      DATE,

                                Prof_Sal                NUMBER(8,2),

                                Prof_Dept             CHAR(6)

                                );

                                CREATE TABLE Student

                                (Stu_ID                  NUMBER(4) Constraint pk_Student Primary Key,

                                Stu_Lname           VARCHAR2(15)                 NOT NULL,

                                Stu_Major            CHAR(6),

Stu_CredHrs         NUMBER(4),

                                Stu_GradePts       NUMBER(5),

                                Prof_ID                 NUMBER(3),

                                CONSTRAINT fk_Student_Prof_ID FOREIGN KEY(Prof_ID)

                                                REFERENCES Professor

                                );

Hand in: Print out of the Create commands, the system response and a DESCRIBE of the tables.

6. (15 Points) Insert the following data into the tables created above using SQL INSERT commands.

Develop a simple point-to-point Message communication system(Java Message Service) using ActiveMQ. Provide the necessary code.

Using C++,

Write a program that will use pointer syntax to access variables, dynamically allocate memories, and pass pointers to functions.

1.            The program should ask the user to enter a size to the array.

2.            The program should dynamically allocate an array with the size.

3.            The program should then ask user to input values to the array

4.            The program should then find the maximum, display all elements forward and reversed using two different ways of pointer access

5.            The program must use functions with pointers as parameters.

6.            The manipulation/access of the array must be done through pointer syntax.

7.            Your main function should only declare the variables and call the functions.

Variable:

You’ll need the following pointer to be declared in your main function.

float * ptData;

Data Validation:

1.            The size of the array cannot be less or equal to 1 (E.g. 2, 5, 100 is fine, but 1 or 0 is no acceptable).

2.            Check if pointer has successfully allocated the array.

Functions:

               You should have separate functions to handle user input, maximum, and display the array (all the values needs to be returned to the function call, you need to have pointer as the input parameter). Main function should only call other functions.

Sample Output:

A load ZL = 80− j100 is located at z = 0 on a lossless 50- line.
The operating frequency is 200 MHz and the wavelength on the line is 2 m.
(a) If the line is 0.8 m in length, use the Smith chart to find the input impedance.
(b) What is s? (c) What is the distance from the load to the nearest voltage
maximum? (d) What is the distance from the input to the nearest point at which
the remainder of the line could be replaced by a pure resistance?

This week we really want to learn about a file I/O in Java.

In Java:

1) Create a plain empty text file named contacts.

2) Populate the text file with a person's name and account number on each line(Joe Doe 123456789). Create 10 accounts.

3) Store that file in the same location as your project

4) Write a program that will find that file and load it into the computers memory.

5) Read each line of the file and print the associated name but NOT the account number (remember the account number is 9 characters fixed)

Write a python program to create a list of integers using random function. Use map function to process the list on the series: x + x2/2! + x3/3! + ….n and store the mapped elements in another list. Assume the value of n as 10
