 * Title:   Compare Version Numbers
 * Auther:  @imcoddy
 * Content: 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 < 13.37
 *
 * Credits:Special thanks to @ts for adding this problem and creating all test cases.
