A school has 100 lockers and 100 students. All lockers are closed on the first day of school. As the students enter, the first student, denoted S1, opens every locker. Then the second student, S2, begins with the second locker, denoted L2, and closes every other locker (i.e. every even numbered locker). Student S3 begins with the third locker and changes every third locker (closes it if it was open, and opens it if it was closed). Student S4 begins with locker L4 and changes every fourth locker. StudentS5 starts with L5 and changes every fifth locker, and so on, until student S100 changes L100.After all the students have passed through the building and changed the lockers, which lockers areopen? Write a program to find your answer.(Hint: Use an array of 100 boolean elements. each of which indicates whether a locker is open (true) or closed (false). Initially, all lockers are closed.)
Solution :
public class NewMain {
public_static void main_(String[] args) {
boolean[] _locker = new boolean_[101];
// to set all the locks to a false NOTE: first locker is the number 0. Last locker is the 99.
for (int_i=1;i<locker_length; i++)
{
locker[i] = false;
}
// first student opens all lockers.
for (int i=1;i<locker.length; i++) {
locker[i] = true;
}
for(int S=2; S<locker.length; S++)
{
for(int k=S; k<locker.length; k=k+S)
{
if(locker[k]==false) locker[k] = true;
else locker[k] = false;
}
}
for(int S=1; S<locker.length; S++)
{
if (locker[S] == true) {
System.out.println("Locker " + S + " Open");
}
/* else {
System.out.println("Locker " + S + " Close");
} */
}
}
}

Write a program that computes how much each person in a group needs to pay (after tax and tip) when splitting the bill equally. Specifically, your program should: 1. Ask a user for the number of people in the party 2. Ask a user for the total bill amount before tax and tip 3. Output the amount due per person after tax and tip Assume that tax is 7.25%, and tip is 20% (tip is before tax).
5.18 LAB: Output numbers in reverse Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a comma, including the last one. Ex: If the input is: 5 2 4 6 8 10 the output is: 10,8,6,4,2, To achieve the above, first read the integers into a vector. Then output the vector in reverse.
Answer:
In C++:
#include<iostream>
#include<vector>
using namespace std;
int main(){
int len, num;
vector<int> vect;
cout<<"Length: ";
cin>>len;
for(int i = 0; i<len;i++){
cin>>num;
vect.push_back(num);}
vector<int>::iterator iter;
for (iter = vect.end() - 1; iter >= vect.begin(); iter--){
cout << *iter << ", ";}
}
Explanation:
This declares the length of vector and input number as integer
int len, num;
This declares an integer vector
vector<int> vect;
This prompts the user for length
cout<<"Length: ";
This gets the input for length
cin>>len;
The following iteration gets input into the vector
for(int i = 0; i<len;i++){
cin>>num;
vect.push_back(num);}
This declares an iterator for the vector
vector<int>::iterator iter;
The following iterates from the end to the beginning and prints the vector in reverse
for (iter = vect.end() - 1; iter >= vect.begin(); iter--){
cout << *iter << ", ";}

A data science experiment you are conducting has retrieved two historical observations for the price of Bitcoin(BTC) on December 2, 2017 of 11234 and 12475. Create a Python script that stores these two historicalobservations in a list variable namedbtcdec1.Your data science experiment requires four additional data tasks. The first task is to use the listappend()method to add the BTC price of 14560 to the listbtcdec1. The second task is to create a new empty listnamedbtcdec2and append the BTC prices of 15630, 12475, and 14972. The third task required you to usethe listextend()method to add the contents ofbtcdec2into the listbtcdec1. The fourth and final taskrequires you to use the listsort()method of the listbtcdec1to sort the items in the newly extended list,then use theprintstatement to output the content of listbtcdec1to the Python console.Starter code:_______.
Answer:
Following are the code to this question:
btcdec1=[11234, 12475] #defining a list btcdec1 that holds two integer values
btcdec1.append(14560)#using append method to add value in btcdec1 list
btcdec2=[]#defining an empty list btcdec2
btcdec2.append(15630)#using append method to add value in btcdec2 list
btcdec2.append(12475)#using append method to add value in btcdec2 list
btcdec2.append(14972)#using append method to add value in btcdec2 list
btcdec1.extend(btcdec2)#using the extend method to add value list into btcdec1
btcdec1.sort()#using sort method to arrange value in ascending order
print(btcdec1)#print list btcdec1
Output:
[11234, 12475, 12475, 14560, 14972, 15630]
Explanation:
In this code a list "btcdec1" is declared, which holds two integer variables, in the next step, it uses the append method to add another element into the list.
In the next step, another empty list "btcdec2" is declared, which uses the append method to hold the integer element, and uses the extend and sort method to add the second list into the first one and then sort the whole list and print its values.

Write a program that asks the user to enter a date in MM/DD/YYYY format that is typical for the US, the Philippines, Palau, Canada, and Micronesia. For the convenience of users from other nations, the program computes and displays this date in an alternative DD.MM.YYYY format. Sample run of your program would look like this: Please enter date in MM/DD/YYYY format: 7/4/1776 Here is the formatted date: 04.07.1776 You can assume that the user will enter correctly formatted date, but do not count on having 0s in front of one-digit dates. Hint: you will need to use string addition (concatenation) here.
Answer:
In Python:
txt = input("Date in MM/DD/YYYY format: ")
x = txt.split("/")
date=x[1]+"."
if(int(x[1])<10):
if not(x[1][0]=="0"):
date="0"+x[1]+"."
else:
date=x[1]+"."
if(int(x[0])<10):
if not(x[0][0]=="0"):
date+="0"+x[0]+"."+x[2]
else:
date+=x[0]+"."+x[2]
else:
date+=x[0]+"."+x[2]
print(date)
Explanation:
From the question, we understand that the input is in MM/DD/YYYY format and the output is in DD/MM/YYYY format/
The program explanation is as follows:
This prompts the user for date in MM/DD/YYYY format
txt = input("Date in MM/DD/YYYY format: ")
This splits the texts into units (MM, DD and YYYY)
x = txt.split("/")
This calculates the DD of the output
date=x[1]+"."
This checks if the DD is less than 10 (i..e 1 or 01 to 9 or 09)
if(int(x[1])<10):
If true, this checks if the first digit of DD is not 0.
if not(x[1][0]=="0"):
If true, the prefix 0 is added to DD
date="0"+x[1]+"."
else:
If otherwise, no 0 is added to DD
date=x[1]+"."
This checks if the MM is less than 10 (i..e 1 or 01 to 9 or 09)
if(int(x[0])<10):
If true, this checks if the first digit of MM is not 0.
if not(x[0][0]=="0"):
If true, the prefix 0 is added to MM and the full date is generated
date+="0"+x[0]+"."+x[2]
else:
If otherwise, no 0 is added to MM and the full date is generated
date+=x[0]+"."+x[2]
else:
If MM is greater than 10, no operation is carried out before the date is generated
date+=x[0]+"."+x[2]
This prints the new date
print(date)

You are working with an online tech service to fix a problem with installation of a program on your machine. You grant them remote access to your computer to enable them to act as you to fix situation. What type of must be installed on your machine to allow this type of action by another person
Answer:
Single User OS.
Explanation:
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.
There are different types of operating systems (OS) used for specific purposes and these are;
1. Batch Operating System.
2. Multitasking/Time Sharing OS.
3. Multiprocessing OS.
4. Network OS.
5. Mobile OS.
6. Real Time OS .
7. Distributed OS.
8. Single User OS.
A Single User OS is a type of operating system that only allows one user to perform a task or use a system at any time.
In this scenario, you are working with an online tech service to fix a problem with installation of a program on your machine. You grant them remote access to your computer to enable them to act as you to fix situation. Therefore, the type of OS which must be installed on your machine to allow this type of action by another person is called a Single User OS.
Write a print statement that uses an f-string to output $5,242.83
Answer:
print("${:,.2f}".format(5242.83))
Explanation:
Given
$5,242.83
Required
Use an f string to output the above
The syntax of an f-string to format a number in that regard is: "${:,.2f}".format(number)
$ means that a dollar sign be printed before the required number
., means that the number be separated with commas
2f means that the number be presented in 2 decimal places
So:
"${:,.2f}".format(number) becomes
"${:,.2f}".format(5242.83)
In a print statement, the full instruction is:
print("${:,.2f}".format(5242.83))

List and fully describe at least 3 examples of input devices and how they are applied in the real world. (In separate paragraphs.)
Answer:
1. Mouse
2.Graphic Tablet
3.Keyboard
Explanation:
1. A computer mouse (plural mice, rarely mouses) is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface of a computer.
2.Graphic tablets, because of their stylus-based interface and ability to detect some or all of pressure, tilt, and other attributes of the stylus and its interaction with the tablet, are widely considered to offer a very natural way to create computer graphics, especially two-dimensional computer graphics
3.A keyboard is for putting information including letters, words and numbers into your computer. You press the individual buttons on the keyboard when you type. The number keys across the top of the keyboard are also found on the right of the keyboard. The letter keys are in the centre of the keyboard.
In Linux, users are internally represented using a unique number called user ID or uid.
a. True
b. False
Answer:
a. True
Explanation:
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.
In Linux, users are internally represented using a unique number called user ID or UID. Thus, this unique number serves as an internal identifier in the Linux Kernel and as such determines what system resources may be accessible to each user. Oftentimes, these unique numbers are not put into use but rather a name is linked with the number and are used instead.
Also, users can be organized logically into a group and are represented uniquely with a group ID or GID, which serves as a global identifier for the users.

2. BIOS is contained in ROM and not in RAM. Can you guess why?
Answer:
Because RAM is only used for short term storage (and doesn't contain anything that will need to be accessed often) RAM it loses its contents when turned off. So when you power on a computer, it has to start running bootup code which has to be stored in ROM
