Problem Statement

X and A are integers between 0 and 9 (inclusive).

If X is less than A, print 0; if X is not less than A, print 10.

Constraints

0 \leq X, A \leq 9

All values in input are integers.

Input

Input is given from Standard Input in the following format:

X A

Output

If X is less than A, print 0; if X is not less than A, print 10.

Sample Input 1

3 5

Sample Output 1

0

3 is less than 5, so we should print 0.

Sample Input 2

7 5

Sample Output 2

10

7 is not less than 5, so we should print 10.

Sample Input 3

6 6

Sample Output 3

10

6 is not less than 6, so we should print 10.
