String Comparison

Problem Description

Given 2 strings of the same size, determine which string is lexicographically smaller. In this

problem, you can assume that the letter's case does not matter, i.e. the uppercase letter is the same as

the corresponding lowercase letter. Output:

0 if string1 equals to string2.

1 if string1 is lexicographically smaller than string2

2 if string2 is lexicographically smaller than string1.

The strings contain only uppercase and lowercase Latin letters.

Input

The first line of the input contains string1.

The second line of the input contains string2.

The length of both strings does not exist 100. (1 <= |string1|, |string2| <= 100).

Output

Output 0, 1, or 2 based on the comparison described above.
