Problem:
A/B Problem

Write a program which reads two integers a and b, and calculates the following values:

a ÷ b: d (in integer)

remainder of a ÷ b: r (in integer)

a ÷ b: f (in real number)

Input

Two integers a and b are given in a line.

Output

Print d, r and f separated by a space in a line. For f, the output should not contain an absolute error greater than 10-5.

Constraints

1 ≤ a, b ≤ 109

Sample Input 1

3 2

Sample Output 1

1 1 1.50000

Solution in JAVA (judge verdict: Accepted)

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main {

	public static void main(String[] args){

		String str = null;
		BufferedReader br = null;
		br = new BufferedReader(new InputStreamReader(System.in));
		
		
		String[] str1;
		int a,b,c,d,r;
		double f;
		try {
			str = br.readLine();
		} catch (IOException e) {
			// TODO ????????????????????? catch ????????????
			e.printStackTrace();
		}
		
		
		str1 = str.split(" ");
		a = Integer.parseInt(str1[0]);
		b = Integer.parseInt(str1[1]);
		d=a/b;
		r=a%b;
		
		f=(double)a/b;
		
		System.out.printf("%d %d %.5f",d,r,f);
		}
}
