Answer:
Explanation:
This program is written in Python. It is a function that takes in two arrays. Then it loops through the first array twice, adding each element with the others and comparing the sum to the values in the second array. If a similar value is found in the second array, the program prints out the value and returns True to the user. Otherwise, it returns False. A test case has been created with two array variables that print out False, the output can be seen in the attached image below.
def sumArray(arr1, arr2):
for i in range(len(arr1)):
for x in range(len(arr1)):
sum = 0
if i != x:
sum = arr1[i] + arr1[x]
if sum in arr2:
print(str(sum) + "Found in Second Array")
return True
return False
arr1 = [1, 9, 10, 44]
arr2 = [2, 4, 8, 14]
print(sumArray(arr1, arr2))
<h2>Answer:</h2>
//import the Scanner class to allow for user input
import java.util.Scanner;
//Begin class definition
public class FirstAndLast{
//Begin the main method
public static void main(String []args){
//****create an object of the Scanner class.
//Call the object 'input' to receive user's input
//from the console.
Scanner input = new Scanner(System.in);
//****create a prompt to tell the user what to do.
System.out.println("Enter the string");
//****receive the user's input
//And store it in a String variable called 'str'
String str = input.next();
//****get and print the first character.
//substring(0, 1) - means get all the characters starting
//from the lower bound (index 0) up to, but not including the upper
//bound(index 1).
//That technically means the first character.
System.out.print(str.substring(0,1));
//****get and print the last character
//1. str.length() will return the number of character in the string 'str'.
//This is also the length of the string
//2. substring(str.length() - 1) - means get all the characters starting
// from index that is one less than the length of the string to the last
// index (since an upper bound is not specified).
// This technically means the last character.
System.out.print(str.substring(str.length()-1));
} // end of main method
} //end of class definition
