Related sum of the halves of a number X84338
Given a non-negative integer n, compute the sum of the digits in the first and in the second halves of n. Your program must also indicate the order relationship among those quantities. This computation has to be done only when the number of digits of n is even.
The first half of a number with l
digits (for even l) is formed by the l/2 left digits and the second half is formed by
the l/2 right digits. For
example, the number 70724444, has first half 7072 and second half 4444.
Input
The input is a non-negative integer n with 0 ≤ n < 231.
Output
The sum of the digits of the first half and the sum of the digits of the second half together with their relationship, provided that the number of digits is even.
Follow the format of the examples.
