Compare two version numbers version1 and version1.
If version1 > version2 output 1, if version1 < version2 output -1, otherwise output 0.
You may assume that the version strings are non-empty and contain only digits and the
. character does not represent a decimal point and is used to separate number sequences.
2.5 is not "two and a half" or "half way to version three", it is the fifth second-level revision of the second first-level revision.
Here is an example of version numbers ordering:
0.1 < 1.1 < 1.2 < 13.37 < 13.37.2
There are multipe test cases.
The first line contain a positive integer N. means there are N test cases.
Following N lines, for each line contains two version numbers V1 and V2 sperated by space.
One line for each test case. Print -1 if V1<V2, 0 if V1=V2, 1 if V1>V2.
3 1.2 1.21 1.44 1.3 13.1.2 13.1.2
-1 1 0
