In the following series, same integer is expressed in different number system. Determine the missing number of the series. a) 10000, 121, 10101, 210, ? , 41, 33, ? , 25, 23, 21, 1A, ? code example

Example 1: Given a double-precision number, , denoting an amount of money, use the NumberFormat class' getCurrencyInstance method to convert into the US, Indian, Chinese, and French currency formats

import java.util.Scanner;
import java.text.NumberFormat;
import java.util.Locale;

public class Solution {
    
    public static void main(String[] args) {
        /* Read input */
        Scanner scanner = new Scanner(System.in);
        double payment = scanner.nextDouble();
        scanner.close();

        /* Create custom Locale for India. 
          I used the "IANA Language Subtag Registry" to find India's country code */
        Locale indiaLocale = new Locale("en", "IN");

        /* Create NumberFormats using Locales */
        NumberFormat us     = NumberFormat.getCurrencyInstance(Locale.US);
        NumberFormat india  = NumberFormat.getCurrencyInstance(indiaLocale);
        NumberFormat china  = NumberFormat.getCurrencyInstance(Locale.CHINA);
        NumberFormat france = NumberFormat.getCurrencyInstance(Locale.FRANCE);

        /* Print output */        
        System.out.println("US: "     + us.format(payment));
        System.out.println("India: "  + india.format(payment));
        System.out.println("China: "  + china.format(payment));
        System.out.println("France: " + france.format(payment));
    }
}

Example 2: Write a function that accepts as input two sets represented as lists and produces at output a list representing the intersection of the two sets. Example: >(union ’(a b c d e f) ’(a c f e x y)) ; Value: (a b c d e f x y)

(define (checkresult a b)
  (list (subtract a b)
        (subtract b a)
        (union a b)
        (intersect a b)))
