Answer:

Explanation:

readline() method is used to read one line from a file. It returns that line from the file.

This line from the file is returned as a string. This string contains a \n at the end which is called a new line character.

So the readline method reads text until an end of line symbol is encountered, and this end of line character is represented by \n.

For example if the file "abc.txt" contains the lines:

Welcome to abc file.

This file is for demonstrating how read line works.

Consider the following code:

f = open("abc.txt", "r") #opens the file in read mode

print(f.readline()) # read one line from file and displays it

The output is:

Welcome to abc file.

The readline() method reads one line and the print method displays that line.

Wendy is an attacker who recently gained access to a vulnerable web server running Microsoft Windows. What command can she use t

VikaD [51]

Answer:

I would say that if she is connected to the server and has grained access to the server, Wendy would have to use the command shortkey win+r (to run) or she could just use the "Type here to search" function.

Then you can type the words "cmd" to bring up the command prompt

Lastly, she would need to use the protocol scp to transfer files. Wendy might need to include a destination for the files to be directed to.

Answer:

-1

Process finished with exit code 0

Explanation: see code bellow

public class BinarySearchRecursive {

public static int binarySearch(int[] a, int key) {

return binarySearchRecursiveHelper(a, key, 0, a.length - 1);

}

public static int binarySearchRecursiveHelper(int[] arr, int target, int start, int end) {

if (start > end) {

return -1;

}

int mid = (start + end) / 2;

if (arr[mid] == target) {

return mid;

} else if (target < arr[mid]) {

return binarySearchRecursiveHelper(arr, target, start, mid - 1);

} else {

return binarySearchRecursiveHelper(arr, target, mid + 1, end);

}

public static void main(String[] args) {

int[] a = {-4, 2, 7, 10, 15, 20, 22, 25, 30, 36, 42, 50, 56, 68, 85, 92, 103};

int index = binarySearch(a, 42); // 10

System.out.println(index);

index = binarySearch(a, 66); // -1

System.out.println(index);

}
