Define a function below, filter_out_strs, which takes a single argument of type list. Complete the function so that it returns a list that contains only the non-strings from the original list. It is acceptable to return an empty list if there are only strings in the original list. This question uses the filter pattern discussed in lecture.
Answers
Answer:
Explanation:
The following code is written in Python and is a simple function that removes all of the type String elements within the list that has been passed as an argument. Then finally, prints out the list and returns it to the user.
def filter_out_str(list):
for x in list:
if type(x) == type(" "):
list.remove(x)
print(list)
return list
Following are the python code to hold only string value into another list by using the given method:
Python code:def filter_only_strs(l):#defining the method filter_only_strs that takes list type variable l in parameter
r = []#defining an empty list r
for x in l:#defining a loop that counts value of list
if isinstance(x, str):#using if block that check list value is in string
r.append(x)#using an empty list that holds string value
return r#return list value
l=['d',12,33,"data"]#defining a list l
print(filter_only_strs(l))#calling the method filter_only_strs
Output:
Please find the attached file.
Program Explanation:
Defining the method "filter_out_strs", which takes one argument of list type that is "l".Inside the method, an empty list "r" is defined, and in the next line, a for loop is declared.Inside the for loop list "l" is used with a conditional statement that uses the "isinstance" method that checks string value in the list and adds its value in "r", and returns its value.Find out more about the list in python here:

Explanation:
Write a function named printPattern that takes three arguments: a character and two integers. The character is to be printed. The first integer specifies the number of times that the character is to be printed on a line (repetitions), and the second integer specifies the number of lines that are to be printed. Also, your function must return an integer indicating the number of lines multiplied by the number of repetitions. Write a program that makes use of this function. That is in the main function you must read the inputs from the user (the character, and the two integers) and then call your function to do the printing.
Answers
Answer:
import java.util.Scanner;
public class Main
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
char c;
int n1, n2;
System.out.print("Enter the character: ");
c = input.next().charAt(0);
System.out.print("Enter the number of times that the character is to be printed on a line: ");
n1 = input.nextInt();
System.out.print("Enter the number of lines that are to be printed: ");
n2 = input.nextInt();
printPattern(c, n1, n2);
}
public static int printPattern(char c, int n1, int n2){
for (int i=0; i<n2; i++){
for (int j=0; j<n1; j++){
System.out.print(c);
}
System.out.println();
}
return n1 * n2;
}
}
Explanation:
*The code is in Java.
Create a function named printPattern that takes one character c, and two integers n1, n2 as parameters
Inside the function:
Create a nested for loop. Since n2 represents the number of lines, the outer loop needs to iterate n2 times. Since n1 represents the number of times that the character is to be printed, the inner loop iterates n1 times. Inside the inner loop, print the c. Also, to have a new line after the character is printed n1 times on a line, we need to write a print statement after the inner loop.
Return the n1 * n2
Inside the main:
Declare the variables
Ask the user to enter the values for c, n1 and n2
Call the function with these values

Explanation:
BGP neighbor relationships formed "They are set up manually."
This is explained between when the BGP developed a close to a neighbor with other BGP routers, the BGP neighbor is then fully made manually with the help of TCP port 179 to connect and form the relationship between the BGP neighbor, this is then followed up through the interaction of any routing data between them.
For BGP neighbors relationship to become established it succeeds through various phases, which are:
1. Idle
2. Connect
3. Active
4. OpenSent
5. OpenConfirm

Write a method, public static int insertSort(ArrayList list), which implements a insertion sort on the ArrayList of Integer objects list. In addition your insertSort method should return an int which represents a statement execution count recording how many times two elements from the ArrayList are compared. For example, if the parameter list prints as [3, 7, 2, 9, 1, 7] before a call to insertSort, it should print as [1, 2, 3, 7, 7, 9] after the method call. This call should return the value 10 since 10 values need to be compared to implement an insertion sort on this array.
Answers
Answer:
Here is the basics of insertionSort performed on an array of integers, this should get you started:

Answers
Answer:
In Python:
fname = input("Filename: ")
a_file = open(fname)
lines = a_file.readlines()
print("Name\t\tHours\t\tTotal Pay")
for line in lines:
eachline = line.rstrip(" ")
for cont in eachline:
print(cont,end="\t")
print()
Explanation:
This prompts the user for file name
fname = input("Filename: ")
This opens the file
a_file = open(fname)
This reads the lines of the file
lines = a_file.readlines()
This prints the header of the report
print("Name\t\tHours\t\tTotal Pay")
This iterates through the content of each line
for line in lines:
This splits each line into tokens
eachline = line.rstrip(" ")
This iterates through the token and print the content of the file
for cont in eachline:
print(cont,end="\t")

A function prototype ... specifies the function's name and type signature, but omits the function implementation. specifies the function's implementation, but omits the function's name and type signature. creates multiple functions with different argument lists. is used as an initial example of a correct function signature. overloads an existing function to accept other argument types.
Answers
Answer:
specifies the function's name and type signature, but omits the function implementation.
Explanation:
I will answer the question with the following illustration in C++:
double func(int a);
The above is a function prototype, and it contains the following:
double -> The function type
func -> The function name
int a -> The signature which in this case, is the parameter being passed to the function
Notice that the above does not include the function body or the implementation.
Hence, (a) is correct

Answers
no longer returns an error but your math seems to have something wrong with it, always returns 0
Console.WriteLine("Enter a percentage here");
int Percent = int.Parse(Console.ReadLine());
Console.WriteLine("Enter your number here");
int Number = int.Parse(Console.ReadLine());
int result = Percent / 100 * Number;

Lists and Procedures Pseudocode Practice For each situation, provide a pseudocoded algorithm that would accomplish the task. Make sure to indent where appropriate. Situation A Write a program that: Takes the list lotsOfNumbers and uses a loop to find the sum of all of the odd numbers in the list (hint: use Mod). Displays the sum. Situation B Write a procedure that takes
Answers
Answer:
The pseudocoded algorithm is as follows:
Procedure sumOdd(lotsOfNumbers):
oddSum = 0
len = length(lotsOfNumbers)
for i = 0 to len - 1
if lotsOfNumbers[i] Mod 2 != 0:
OddSum = OddSum + lotsOfNumbers[i]
Print(OddSum)
Explanation:
This defines the procedure
Procedure sumOdd(lotsOfNumbers):
This initializes the oddSum to 0
oddSum = 0
This calculates the length of the list
len = length(lotsOfNumbers)
This iterates through the list
for i = 0 to len-1
This checks if current list item is odd
if lotsOfNumbers[i] Mod 2 != 0:
If yes, the number is added to OddSum
OddSum = OddSum + lotsOfNumbers[i]
This prints the calculated sum
Print(OddSum)
)Assume passwords are limited to the use of the 95 printable ASCII characters and that all passwords are 10 characters in length. Assume a password cracker with an encryption rate of 6.4 million encryptions per second. How long will it take to test exhaustively all possible passwords on a UNIX system
Answers
Answer:
296653 years
Explanation:
The length of password = 10
To get possible password:
95 printable password raised to power 10
= 95¹⁰
Then we calculate time it would take to break password
95¹⁰/6.4million
95¹⁰/6400000
= 9355264675599.67 seconds
From here we get minutes it would take. 60 secs = 1 min
= 9355264675599.67/60
= 155921077927 minutes
From here we get number of hours it would take 1 hr = 60 mins
155921077927/60
= 2598684632 hours
From here we calculate number of days it would take. 24 hrs = 1 day
2598684632/24
= 108278526 days
From here we calculate number of years it would take. 365 days = 1 ye
= 108278526/365
= 296653 years
It would take this number of years to test all possible passwords
