    Java solution - passes 100% of test cases

    The tricky part is creating a custom local for India. I had to look up India's country code in the IANA Language Subtag Registry. If anyone had an easier way to find it please let me know.

    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));
    }
}
