[LeetCode]Compare Version Numbers

2015-01-24 05:33:15 · 作者: · 浏览: 3

Compare two version numbers version1 and version1.
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

public class Solution {
    public int compareVersion(String version1, String version2) {
        String[] v1 = version1.split("\\.");
        String[] v2 = version2.split("\\.");
        for(String s:v1){
        	System.out.println(s);
        }
        for(int i=0;i
  
   n2){
        		return 1;
        	}else if(n1
   
    0) return -1; } }else if(v1.length>v2.length){ for(int i=v2.length;i
    
     0) return 1; } } return 0; } }
