A **xylem** number is a number such that the sum of extreme digits equals the sum of the mean digits. Otherwise the number is considered as the **phloem** number.

Write a program in **Java** to accept a positive integer from the user. Check whether it is a xylem number or a phloem number.

**Example**:

INPUT:

N = 12348

OUTPUT:

Sum of extreme digits = 1 + 8 = 9.

Sum of mean digits = 2 + 3 + 4 = 9.

Thus, 12348 is a xylem number.

```
import java.io.*;
class Xylem{
public static void main(String args[])throws IOException{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.print("N = ");
int num = Math.abs(Integer.parseInt(br.readLine()));
int extreme = 0;
int mean = 0;
int copy = num;
while(copy != 0){
if(copy == num || copy < 10)
extreme += copy % 10;
else
mean += copy % 10;
copy /= 10;
}
System.out.println("Sum of extreme digits: " + extreme);
System.out.println("Sum of mean digits: " + mean);
if(extreme == mean)
System.out.println(num + " is a xylem number.");
else
System.out.println(num + " is a phloem number.");
}
}
```
