double product, sum = 0;

    Scanner sc = new Scanner(System.in);
    System.out.print("Enter the Number of Terms: ");
    int n = sc.nextInt();

    double[] x = new double[n];
    double[] y = new double[n];

    System.out.println("Enter all the x, y terms: ");
    for (int i = 0; i < n; i++) {
        x[i] = sc.nextDouble();
        y[i] = sc.nextDouble();
    }

    System.out.println("x = {" + Arrays.toString(x) + "}");
    System.out.println("x = {" + Arrays.toString(y) + "}");

    System.out.print("Enter a point to Find it's value: ");
    int xPoint = sc.nextInt();
    // End of inputs

    product = 1;
    // Peforming Arithmatic Operation
    for (int i = 0; i < n; i++) {
        for (int j = 0; j < n; j++) {
            if (j != i) {
                product *= (xPoint - x[j]) / (x[i] - x[j]);
            }
        }
        sum += product * y[i];

        product = 1;    // Must set to 1
    }
    System.out.println("The value at point " + xPoint + " is : " + sum);

    // End of the Program
}
