Write and export as default the function comparing given versions, version1 and version2. If version1 > version2, the function should return 1, if version1 < version2 then -1, and if version1 === version2 then 0.

Version is a string containing two numbers (major and minor versions) separated by a dot, e.g. 12.11. Note that a version is not a floating-point number but several unrelated numbers. To test if a version is higher/lower you should compare each number independently. Thus, version 0.12 is higher than version 0.2.

Example of versions order:

0.1 < 1.1 < 1.2 < 1.11 < 13.37

Examples

compareVersion("0.1", "0.2"); // -1

compareVersion("0.2", "0.1"); // 1

compareVersion("4.2", "4.2"); // 0
