165. Compare Version Numbers
Problem: 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. Example 1: Input: version1 = "0.1", version2 = "1.1" Output: -1 Example 2: Input: version1 = "1.0.1", version2 = "1" Output: 1 Example 3: Input: version1 = "7.5.2.4", version2 = "7.5.3" Output: -1 Analysis: 这道题实现的时候要注意在数组越界的时候把值赋为零。 Solution: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 class Solution { public int compareVersion ...
