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:0Explanation:Ignoring leading zeroes, both "01" and "001" represent the same integer "1".

**Example 2:**

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

**Example 3:**

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

**Example 4:**

Input:version1 = "1.0.1", version2 = "1"Output:1

**Example 5:**

Input:version1 = "7.5.2.4", version2 = "7.5.3"Output:-1

**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**.
