Xylem Phloem Number

Xylem Number is a number whose sum of extreme (last and first) digits is equal to sum of it’s mean (all other digits except last and first) digits.

Phloem Number is a number which does not hold the above condition.

Example 1: 21201. 2+1 = 1+2+0. We observer sum of extremes and means are equal. Hence it is a Xylem Number.

Example 2: 21211. 2+1 != 1+2+1. Here sum of extremes and means are not equal. Hence it is a Phloem Number.

#include <stdio.h>
void main()
{
    int n=0,r=0,nCopy=0,eSum=0,mSum=0;
    printf("Enter a number: ");
    scanf("%d",&n);
    nCopy=n;
    while(n>0)
    {
        r=n%10;
        if(n==nCopy||n<10)
        {
            eSum=eSum+r;
        }
        else
        {
            mSum=mSum+r;
        }
        n=n/10;
    }

    {
        printf("%d is a Xylem Number",nCopy);
    }
    else
    {
        printf("%d is a Phloem Number",nCopy);
    }
