Compare Two Version Numbers
Given two version number strings, determine which is greater by comparing their revision numbers.
Input format
Two lines, each a version string like "1.0.3" (dot-separated non-negative integers).
Output format
Print 1 if the first version is greater, -1 if the second is greater, or 0 if they are equal (missing revisions count as 0).
Constraints
- Values fit in a 64-bit signed integer
- Trailing whitespace and a trailing newline are ignored by the judge
Read from stdin, write to stdout. Sample cases below show the exact format.
