Write a function to calculate refunds example assumed refund driving time period more than 48 hours. Function prototype is as follows:

double CancelFee(double price);

If this question is C / C ++ code delivery submitted only CancelFee function definition part, other content submission, compile error.

 Input:

Enter a real number, the ticket face value.

Sample input: 

106 

Sample output: 

5.5 

code: 

import java.util.*;
public class Main
{
	public static double CancelFee(double price)
	{
		double x=price*0.05;
		double y=(int)x;
		if(x-y<0.25)
			y+=0;
		else if(x-y>=0.25&&x-y<0.75)
			y+=0.5;
		else
			y+=1;
		return y;
	}
	public static void main(String[] args)
	{
		Scanner input=new Scanner(System.in);
		double a=input.nextDouble();
		System.out.printf("%.1f\n",Main.CancelFee(a));
		input.close();
	}
