## Problem Description

A number is divisible by 11 if the absolute difference between the sums of alternating digits is divisible by 11.

For example, 74954 is divisible by 11 because (7 + 9 + 4) - (4 + 5) = 11 is divisible by 11.

You are given a positive integer *N*. Determine if *N* is divisible by 11.

## Input

The only line of input will contain one integer, *N*.

## Output

Output 'YES' (without quotes) on a single line if N is divisible by 11. Otherwise, output 'NO' (without quotes).

## Limits

Subtask 1 (20%): 1 ≤ *N* ≤ 1000000

Subtask 2 (80%): *N* contains at most 1000000 digits
