# Compare Version Numbers InterviewBit Solution

**Problem:** Compare Version Numbers

**Problem Statement:**

Compare two version numbers version1 and version2.

If version1 > version2 return 1,

If version1 < version2 return -1,

otherwise return 0.

You may assume that the version strings are non-empty and contain only digits and the . character. The character does not represent a decimal point and is used to separate number sequences. For instance, 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 < 1.13 < 1.13.4`

**Solution Approach:**

The solution is straightforward, separate each number partitioned by "." character.

Then apply the sorting logic described in the problem statement.
