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.
