Dallas College Create a Java Code Computer Programming Task
Problem Description:
RedEx Corp., a major shipping company has hired you develop a program that computes the shipping cost of packages based on the weight of the package. The company uses the following weight-based rule to compute the shipping cost:
3.75 + ????h? ? 1.25, ?? 0 < ????h? ? 15 ?????h?????? = – 8.50 + (????h? ? 7) ? 1.75, ?? 15 < ????h? ? 25
10.75 + (????h? ? 12) ? 2.25, ?? 25 < ????h? ? 35
Write a program that reads the full name of the user. Next, the program prompts the user to enter the weight of the package and then using the above rule, computes the shipping cost. If the weight of the package is greater than 35, the program should display a message informing the user that the package cannot be shipped. If the weight of the package is 0 or below, the program should display a message informing the user that the weight is not valid.
Sample Runs:
Enter your full name: Billie Eilish
Enter package weight: 8.8
Billie, the total cost for your package is 14.75
Enter your full name: Daenerys Targaryen
Enter package weight: 19.2
Daenerys, the total cost for your package is 29.85
Enter your full name: Bilbo Baggins Enter package weight: 45.2
Bilbo, the package cannot be shipped.
Hints:
Usetheappropriatedatatypetoreadthefullnameandpackageweightenteredby the user.
Extractthefirstnameusingtheappropriatemethodsfromthefullname.
Use the appropriate logical operator to evaluate the range in which the packageweight falls.
Makeuseofthemulti-wayif-elsestatementstodisplaytheappropriateoutput.
Deliverables:
Your .java file including:
1. A sample run with username as “Albus Dumbledore” and package weight as “23.8”. Include this sample run as a comment on top of your Java code.

ENGR 120 Grossmont College Iterative Estimation Matlab Lab Report
Lab 9 – Iterative Estimation
Function and aesthetics are often governed by mathematics. Beautiful examples of this can be found in nature, from the growth pattern of plants to the feature placement on the human face. Read a low-tech blog post (Links to an external site.) about how Aston Martin uses the golden ratio in car design. The Golden Ratio, phi, is defined by:
Equation 1. Exact Phi
One way that phi can be approximated is by taking the limit as n goes to infinity of a term in the Fibonacci sequence divided by it’s proceeding term:
Equation 2. Estimated Phi
Be sure to read the module page on Printing to Log Files because it contains code on how to compute terms of the Fibonacci sequence. Similarly, e can be approximated by:
Equation 3. Estimated E
We will use our new input and output tools to create an iterative estimation program for both e and phi and compare our estimates to the true values.
Procedure
As usual, create a script, include a comment at the top explaining the purpose of the script, your name, and the date it was created.
1. Use the menu function to ask the user if they would like to estimate e or phi. Use the input function to prompt the user to select a desired accuracy (tolerance) between .1 to .01. Include error checking to ensure the user input corresponds to your desired format. See the page on Input Error Checking for an example of how to do this. Use a conditional or switch statement to select between the two estimation functions that you will write (see below).
2. To write your function to estimate e, create a function that accepts as input the user’s desired tolerance and outputs the estimate of e and the number of iterations required to meet the desired accuracy. Your function header will look like: function [myE, numIters] = estE(tol). Use the limit equation above for large n and compare the result to MATLAB’s built-in value for e. While the absolute value of the difference between e and your estimated e is greater than the tolerance, continue looping and increasing n.
3. Use a similar method to estimate phi. Since MATLAB has no built-in constant for phi, create your own true phi using Equation 1 above.
4. Create a text file to keep track of your progress at each iteration with the fprintf command (you may have to print every 100 iterations or even 1000 iterations if it takes a long time to reach the desired accuracy). Report the iteration, the estimated value and the absolute value of the difference between the estimated and true values at each step. Here’s a sample output:
…
After 133 iterations, estimated e is 2.708133 and error is 0.010149.
After 134 iterations, estimated e is 2.708208 and error is 0.010074.
After 135 iterations, estimated e is 2.708282 and error is 0.010000.
You will need to submit .m files for each function you define, main.m, estE.m and estPhi.m as well as your text log file. Each .m file should include your name and function description in comments. Upload your files via Canvas. Let me know if you have any questions!
Marymount University Use of Automatic Methods for Reversing the String Program
Instruction are in the code what you should do
public class Palindrome {
/*
* Implement this method and return true if the word is the same
* forward and backwards
* Do not use automatic methods for reversing the string
*/
private boolean isPalindrome(String word) {
return false;
}
/*
* Open up the file.
* Break into words
* print out all Palindromes
*/
private void findAllPalindromes(String fileName) {
}
public Palindrome() {
//run some tests
if (isPalindrome(“racecar”)) {
System.out.print(“pass”);
}
else {
System.out.print(“Fail”);
}
if (isPalindrome(“mom”)) {
System.out.print(“pass”);
}
else {
System.out.print(“Fail”);
}
if (isPalindrome(“noon”)) {

#Basic Node definition. Each Node contains a Value, a left child, and a right child
class Node:
def __init__(self,value):

self.right = None
self.val = value
#insert Value into the appropiate spot in the tree
def insert(root, node):
