Write a program FindDuplicate.java that reads n integer arguments from the command line into an integer array of length n, where

kozerog [31]

Answer:

public class FindDuplicate{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int n = 5;
int arr[] = new int[n];
for(int i=0; i < arr.length; i++){
int inputNum = input.nextInt();
if(inputNum >=1 && inputNum <=n) {
arr[i] = inputNum;
}
}
for(int j =0; j < arr.length; j++){
for(int k = 0; k < arr.length; k++){
if(j == k){
continue;
}else{
if(arr[j] == arr[k]){
System.out.println("True");
return;
}
}
}
}
System.out.println("False");
}
}

Explanation:

Firstly, create a Scanner object to get user input (Line 4).

Next, create an array with n-size (Line 7) and then create a for-loop to get user repeatedly enter an integer and assign the input value to the array (Line 9 - 14).

Next, create a double layer for-loop to check the each element in the array against the other elements to see if there is any duplication detected and display "True" (Line 21 - 22). If duplication is found the program will display True and terminate the whole program using return (Line 23). The condition set in Line 18 is to ensure the comparison is not between the same element.

If all the elements in the array are unique the if block (Line 21 - 23) won't run and it will proceed to Line 28 to display message "False".

Charlie has a large book collection. He was keeping track of it in a spreadsheet, but it has grown big enough that he wants to c

zepelin [54]

Answer:

Check the explanation

Explanation:

Ans 1) storing the data in one single row comes with its own barriers and that is if you delete one of the record in the spreadsheet, all the equivalent records which you didn't wanted to delete would be deleted. For take for instance, if you wish to delete the record of author "James Taylor" then all the books he has written would also be deleted from the spreadsheet.

Ans 2) In 1NF, all row is expected to have only 1 tuple, but here in this spreadsheet the title field for Author "James Taylor" has 2 books, so it would be separated into single rows.

Ans 3) The table in the attached image below doesn't delete with Delete anomaly, i.e., for author "May Norton" if you delete this record, then the only book written by her would be deleted.

So, you have to convert this table into 2NF.

Make separate tables for Author and Book

Author(Author Name, Author Country)

Books(Author Name, Book title, Publisher, Publisher Location, Year, price)

This cannot be normalized any further.

A signal travels from point A to point B. At point A, the signal power is 100 W. At point B, the power is 90 W. What is the atte

11Alexandr11 [23.1K]

Answer:

$Attenuation = 0.458\ db$

Explanation:

Given

Power at point A = 100W

Power at point B = 90W

Required

Determine the attenuation in decibels

Attenuation is calculated using the following formula

$Attenuation = 10Log_{10}\frac{P_s}{P_d}$

Where $P_s = Power\ Inpu$ t and $P_d = Power\ outpu$ t

$P_s = 100W$

$P_d = 90W$

Substitute these values in the given formula

$Attenuation = 10Log_{10}\frac{P_s}{P_d}$

$Attenuation = 10Log_{10}\frac{100}{90}$

$Attenuation = 10 * 0.04575749056$

$Attenuation = 0.4575749056$

$Attenuation = 0.458\ db$ <em>(Approximated)</em>

A company is performing an analysis on the computers at its main office. The computers are spaced along a single row. The analys

harina [27]

Answer:

array = input("Enter the list of computer memory: ").split(',')

int_arr = [int(x) for x in array]

segment = int(input("Enter the length of segment to analyze: "))

list_len = len(int_arr)

segList = []

mini = []

for x,i in enumerate(int_arr):

seg = int_arr[i-1:segment+i-1]

if len(seg) == segment:

segList.append(seg)

for x in segList:

mini.append(min(x))

result = mini.index(min(mini))

print("Segment with the minimum memory is: ",segList[result])

Explanation:

The python program prints out the segment after analysis, with the smallest disk memory space. The code gets the array of computer rows from the user input and segments the array with the number of segment input, then the minimum is compared for all segments in the network.
