Xylem Phloem Number – SchoolCodeHub

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.
