Answer:
Following are the response to the given question:
Explanation:
The glamorous objective is to examine the items (as being the most valuable and "cheapest" items are chosen) while no item is selectable - in other words, the loading can be reached.
Assume that such a strategy also isn't optimum, this is that there is the set of items not including one of the selfish strategy items (say, i-th item), but instead a heavy, less valuable item j, with j > i and is optimal.
As [tex]W_i < w_j[/tex], the i-th item may be substituted by the j-th item, as well as the overall load is still sustainable. Moreover, because [tex]v_i>v_j[/tex] and this strategy is better, our total profit has dropped. Contradiction.
The following method is intended to return true if and only if the parameter val is a multiple of 4 but is not a multiple of 100 unless it is also a multiple of 400. The method does not always work correctly public boolean isLeapYear(int val) if ((val 4) == 0) return true; else return (val & 400) == 0; Which of the following method calls will return an incorrect response?
A .isLeapYear (1900)
B. isLeapYear (1984)
C. isLeapYear (2000)
D. isLeapYear (2001)
E. isLeapYear (2010)
Answer:
.isLeapYear (1900) will return an incorrect response
Explanation:
Given
The above method
Required
Which method call will give an incorrect response
(a) will return an incorrect response because 1900 is not a leap year.
When a year is divisible by 4, there are further checks to do before such year can be confirmed to be a leap year or not.
Since the method only checks for divisibility of 4, then it will return an incorrect response for years (e.g. 1900) that will pass the first check but will eventually fail further checks.
Hence, (a) answers the question;
LAB: Warm up: Drawing a right triangle This program will output a right triangle based on user specified height triangle_height and symbol triangle_char. (1) The given program outputs a fixed-height triangle using a character. Modify the given program to output a right triangle that instead uses the user-specified triangle_char character. (1 pt) (2) Modify the program to use a loop to output a right triangle of height triangle_height. The first line will have one user-specified character, such as % or* Each subsequent line will have one additional user-specified character until the number in the triangle's base reaches triangle_height. Output a space after each user-specified character, including a line's last user-specified character. (2 pts) Example output for triangle_char = % and triangle_height = 5: Enter a character: Enter triangle height: 5 273334.1408726 LAB ACTIVITY 16.6.1: LAB: Warm up: Drawing a right triangle 0/3 main.py Load default template... 1 triangle_char - input('Enter a character:\n') 2 triangle_height = int(input('Enter triangle height:\n')) 3 print('') 4 5 print ('*') 6 print ("**') 7 print ("***') 8
Answer:
The modified program in Python is as follows:
triangle_char = input('Enter a character:\n')
triangle_height = int(input('Enter triangle height:\n'))
for i in range(triangle_height):
print(triangle_char * (i+1))
Explanation:
This gets the character from the user
triangle_char = input('Enter a character:\n')
This gets the height of the triangle from the user
triangle_height = int(input('Enter triangle height:\n'))
This iterates through the height
for i in range(triangle_height):
This prints extra characters up to the height of the triangle
print(triangle_char * (i+1))
Here's the modified program that incorporates the requested changes:
python
Copy code
triangle_char = input('Enter a character:\n')
triangle_height = int(input('Enter triangle height:\n'))
print('')
for i in range(1, triangle_height + 1):
line = triangle_char * i + ' ' * (triangle_height - i)
print(line)
This program uses a loop to iterate from 1 to triangle_height. In each iteration, it creates a line by concatenating triangle_char repeated i times with spaces (' ') repeated (triangle_height - i) times. The resulting line is then printed.
For example, if the user enters % as the character and 5 as the height, the output will be to make sure to maintain the indentation properly in your code for it to work correctly.

what are the different steps while solving a problem using computer? explain
Explanation:
The following six steps must be followed to solve a problem using computer.
Problem Analysis.
Program Design - Algorithm, Flowchart and Pseudocode.
Coding.

Debugging and Testing.
Program Documentation.
(CO 4 and 5) Create a program that will read in a list of test scores from the user and add them to a list. Ask the user in between each score if they want to continue (y/n). Display all of the scores entered and the total score at the end. Using the code below, put the code in the proper order Sample output: Welcome to the Test Score Program Add score: 88.45 Do you want to continue
Answer and Explanation:
Using Javascript:
function AddScores(){
Window.alert("Welcome to the Test Score Program");
var ScoreList= new Array();
ScoreList.push(Prompt("Add Score"));
var WhatNext= Confirm("do you want to continue?");
If(WhatNext===true) {
do{
ScoreList.push(Prompt("Add Score"));
}
While(
Confirm("do you want to continue?")===true;);
}
Alert(ScoreList);
Alert(ScoreList.reduce(function(a,b){return a +b};,0);)
}
AddScores();
From the above code in javascript programming language, we have created a list ScoreList and added elements to it using push method of the array object and a do...while loop that checks the condition and then adds the user's input to the array. We then alerted the array to the screen and then summed up the array elements and also alerted to the screen.

Which XXX declares a student's name.
public class Student {
XXX
private double myGPA;
private int myID;
public int getID() {
return myID;
}
}
Group of answer choices
a. String myName;
b. public String myName;
c. private myName;
d. private String myName;
Answer:private String myName;
Explanation:To declare a student's name, the following should be noted.
i. The name of the student is of type String
ii. Since all of the instance variables (myGPA and myID) have a private access modifier, then myName (which is the variable name used to declare the student's name) should be no exception. In other words, the student's name should also have a private access.
Therefore, XXX which declares a student's name should be written as
private String myName;
Option (a) would have been a correct option if it had the private keyword
Option (b) is not the correct option because it has a public access rather than a private access.
Option (c) is not a valid syntax since, although it has a private access, the data type of the variable myName is not specified.
Option (d) is the correct option.
