It is common for people to name directories as dir1, dir2, and so on. When there are ten or more directories, the operating system displays them in dictionary order, as dir1, dir10, dir11, dir12, dir2, dir3, and so on. That is irritating, and it is easy to fix. Provide a comparator that compares strings that end in digit sequences in a way that makes sense to a human. First compare the part before the digit as strings, and then compare the numeric values of the digits.

Write a program using integers user_num and x as input, and output user_num divided by x three times.Ex: If the input is:20002Then the output is:1000 500 250Note: In Python 3, integer division discards fractions. Ex: 6 // 4 is 1 (the 0.5 is discarded).LAB ACTIVITY2.29.1: LAB: Divide by x0 / 10main.pyLoad default template...12''' Type your code here. '''
Answer:
Following are the code to the given question:
user_num = int(input())#defining a variable user_num that takes input from user-end
x = int(input())#defining a variable x that takes input from user-end
for j in range(3):#defining for loop that divides the value three times
user_num = user_num // x#dividing the value and store integer part
print(user_num)#print value
Output:
2000

1000
500
250
Explanation:
In the above-given program code two-variable "user_num and x" is declared that inputs the value from the user-end and define a for loop that uses the "j" variable with the range method.
In the loop, it divides the "user_num" value with the "x" value and holds the integer part in the "user_num" variable, and prints its value.
Briefly explain what an array is. As part of your answer make use of a labelled example to show the declaration and components of an array
Answer:
Explanation:
In programming an array is simply a grouping of various pieces of data. Various data elements are grouped together into a single set and saved into a variable. This variable can be called which would return the entire set which includes all of the elements. The variable can also be used to access individual elements within the set. In Java an example would be the following...
int[] myArray = {33, 64, 73, 11, 13};
In Java, int[] indicates that the variable will hold an array of integers. myArray is the name of the variable which can be called to access the array elements. The elements themselves (various pieces of data) are located within the brackets {}

Base conversion. Perform the following conversion (you must have to show the steps to get any credit.
3DF16 = ?
Base to be converted to was not included but we would assume conversion to base 10(decimal)
Answer and Explanation:
The 3DF in base 16 is a hex number so we need to convert to its equivalent binary/base 2 form:
We therefore each digit of given hex number 3DF in base 16 to equivalent binary, 4 digits each.
3 = 0011
D = 1101
F = 1111
We then arrange the binary numbers in order
3DF base 16 = 1111011111 in base 2
We then convert to base 10 =
= 1x2^9+1x2^8+1x2^7+1x2^6+0x2^5+1x2^4+1x2^3+1x2^2+1×2^1+1×2^0
= 991 in base 10
Which information can you apply to every page of your document with the page layout options?
header
conclusion
body
footer
introduction
Answer:
Header and footer
Explanation:
The page layout tab usually found in document programs such as Microsoft Word hold options used to configure several page options which is to be applied to a document. The page layout option gives users options to set page margins, orientation, page numbering, indentation and the other page layout options which is primarily how we would like our document to look like when printed. The page layout option also allows the insertion of a header and footer which is a note which can be written at the topmost and bottomost part of the document. Once, a header and footer option is selected, it is applied to every page of the document being worked on at the moment.

1. What is memory mapped I/O?
Answer:
Memory-mapped I/O and port-mapped I/O are two complementary methods of performing input/output between the central processing unit and peripheral devices in a computer. An alternative approach is using dedicated I/O processors, commonly known as channels on mainframe computers, which execute their own instructions.
Assume that an O(log2N) algorithm runs for 10 milliseconds when the input size (N) is 32. What input size makes the algorithm run for 14 milliseconds
Answer:
An input size of N = 128 makes the algorithm run for 14 milliseconds
Explanation:
O(log2N)
This means that the running time for an algorithm of length N is given by:
[tex]F(N) = c\log_{2}{N}[/tex]
In which C is a constant.
Runs for 10 milliseconds when the input size (N) is 32.
This means that [tex]F(32) = 10[/tex]
So
[tex]F(N) = c\log_{2}{N}[/tex]
[tex]10 = c\log_{2}{32}[/tex]
Since [tex]2^5 = 32, \log_{2}{32} = 5[/tex]
Then
[tex]5c = 10[/tex]
[tex]c = \frac{10}{5}[/tex]
[tex]c = 2[/tex]
Thus:
[tex]F(N) = 2\log_{2}{N}[/tex]
What input size makes the algorithm run for 14 milliseconds
N for which [tex]F(N) = 14[/tex]. So
[tex]F(N) = 2\log_{2}{N}[/tex]
[tex]14 = 2\log_{2}{N}[/tex]
[tex]\log_{2}{N} = 7[/tex]
[tex]2^{\log_{2}{N}} = 2^7[/tex]
[tex]N = 128[/tex]
An input size of N = 128 makes the algorithm run for 14 milliseconds

Given an array of n distinct integers sorted in ascending order, write a function that returns a Fixed Point in the array, if there is any Fixed Point present in array, else returns -1. Fixed Point in an array is an index i such that arr[i] is equal to i. Note that integers in array can be negative. Examples: #include using namespace std; void removeDivByFive(int *arr,int& size) { int index=0; for(int i=0;i
Answer:
The function is as follows:
int returnsFixed(int arr [],int n){
int retVal = -1;
for(int i = 0; i<n;i++){
if(i == arr[i]){
retVal = i;
break;
}
}
return retVal;
}
Explanation:
This defines the functionl it receives the array and the length of the array
int returnsFixed(int arr [],int n){
This initializes the return value to -1
int retVal = -1;
This iterates through the array
for(int i = 0; i<n;i++){
This checks if i equals arr[i]
if(i == arr[i]){
If yes, the return value (i.e. the fixed point) is set to i
retVal = i;
And the code is exited
break;
} This ends the if condition
} This ends the iteration
This returns the calculated fixed point
return retVal;
}
Analyze the following code:
// Enter an integer Scanner input = new Scanner(System.in);
int number = input.nextInt(); if (number <= 0) System.out.println(number);
1) The if statement is wrong, because it does not have the else clause;
2) System.out.println(number); must be placed inside braces;
3) If number is zero, number is displayed;
4) If number is positive, number is displayed.
5) number entered from the input cannot be negative.
Answer:
3) If number is zero, number is displayed;
Explanation:
The code snippet created is supposed to take any input number from the user (positive or negative) and print it to the console if it is less than 0. In this code the IF statement does not need an else clause and will work regardless. The System.out.println() statement does not need to be inside braces since it is a simple one line statement. Therefore, the only statement in the question that is actually true would be ...
3) If number is zero, number is displayed;
Answer:
If number is zero, number is displayed
Explanation:
Given
The above code segment
Required
What is true about the code segment
Analyzing the options, we have:
(1) Wrong statement because there is no else clause
The above statement is not a requirement for an if statement to be valid; i.e. an if statement can stand alone in a program
Hence, (1) is false
(2) The print statement must be in { }
There is only one statement (i.e. the print statement) after the if clause. Since the statement is just one, then the print statement does not have to be in {} to be valid.
Hence, (2) is false
(3) number is displayed, if input is 0
In the analysis of the program, we have: number <=0
i.e. the if statement is true for only inputs less than 0 or 0.
Hence, number will be printed and (3) is false
(4) number is displayed for positive inputs
The valid inputs have been explained in (3) above;
Hence, (4) is false.
(5) is also false

write a loop that reads positive integers from stands input and that terinated when it reads an interger that is not positive after the loop termpinates
Loop takes only positive numbers and terminates once it encounters a negative numbers.
Answer and Explanation:
Using javascript:
Var positiveInt= window.prompt("insert positive integer");
While(positiveInt>=0){
Alert("a positive integer");
Var positiveInt= window.prompt("insert positive integer");
}
Or we use the do...while loop
Var positiveInt= window.prompt("insert positive integer");
do{
Var positiveInt= window.prompt("insert positive integer");
}
While (positiveInt>=0);
The above program in javascript checks to see if the input number is negative or positive using the while loop condition and keeps executing with each input until it gets a negative input
Which attack form either exploits a software flaw or floods a system with traffic in order to prevent legitimate activities or transactions from occurring?
Answer:
Denial of service attack.
Explanation:
In Cybersecurity, vulnerability can be defined as any weakness, flaw or defect found in a software application or network and are exploitable by an attacker or hacker to gain an unauthorized access or privileges to sensitive data in a computer system.
This ultimately implies that, vulnerability in a network avail attackers or any threat agent the opportunity to leverage on the flaws, errors, weaknesses or defects found in order to compromise the security of the network.
Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, sniffing, DOS attack, etc.
A denial of service (DOS) attack is a form of cyber attack that involves either the exploitation of a software flaw or overwhelmingly floods a computer system in a network with traffic in order to prevent authorized users from performing legitimate activities or transactions.
Some of the ways to prevent vulnerability or cyber attacks in a network are;
1. Ensure you use a very strong password with complexity through the use of alphanumerics.
2. You should use a two-way authentication service.
3. You should use encrypting software applications or services.

Create and configure databases in oracle database management system operation administration
Answer:
You typically create a database during Oracle Database software installation. However, you can also create a database after installation.
Reasons to create a database after installation are as follows:
You used Oracle Universal Installer (OUI) to install software only, and did not create a database. You want to create another database (and database instance) on the same host computer as an existing Oracle database. In this case, this chapter assumes that the new database uses the same Oracle home as the existing database. You can also create the database in a new Oracle home by running OUI again. You want to make a copy of (clone) a database.
