Given two version numbers, `version1` and `version2`, compare them.

Version numbers consist of one or more revisions joined by a dot `'.'`. Each revision consists of digits and may contain leading zeros. Every revision contains at least one character. Revisions are 0-indexed from left to right, with the leftmost revision being revision 0, the next revision being revision 1, and so on. For example `2.5.33` and `0.1` are valid version numbers.

To compare version numbers, compare their revisions in left-to-right order. Revisions are compared using their integer value ignoring any leading zeros. This means that revisions `1` and `001` are considered equal. If a version number does not specify a revision at an index, then treat the revision as `0`. For example, version `1.0` is less than version `1.1` because their revision 0s are the same, but their revision 1s are `0` and `1` respectively, and `0 < 1`.

Return the following:

- If `version1 < version2`, return `-1`.
- If `version1 > version2`, return `1`.
- Otherwise, return `0`.

Example 1:

    Input: version1 = "1.01", version2 = "1.001"
    Output: 0
    Explanation: Ignoring leading zeroes, both "01" and "001" represent the same integer "1".

Example 2:

    Input: version1 = "1.0", version2 = "1.0.0"
    Output: 0
    Explanation: version1 does not specify revision 2, which means it is treated as "0".

Example 3:

    Input: version1 = "0.1", version2 = "1.1"
    Output: -1
    Explanation: version1's revision 0 is "0", while version2's revision 0 is "1". 0 < 1, so version1 < version2.

Constraints:

- `1 <= version1.length, version2.length <= 500`
- `version1` and `version2` only contain digits and `'.'`.
- `version1` and `version2` are valid version numbers.
- All the given revisions in `version1` and `version2` can be stored in a 32-bit integer.
