Palindrome Number

Check if an integer is a palindrome: a number that reads the same forwards and backwards.

Negative numbers are never palindromes (because of the minus sign). Single-digit numbers are always palindromes.

Input

• Line 1: a single integer (any int value, from -2^31 to 2^31 - 1)

Output

• true if the number is a palindrome, false otherwise.

Examples

Input:
121

Output:
true

Input:
-121

Output:
false

Input:
10

Output:
false

Input:
0

Output:
true

A single-digit number, including 0, always reads the same both ways.
