Leetcode-Compare Version Numbers
判断产品版本号的大小。
public class Solution { public int compareVersion(String version1, String version2) { String[] v1 = version1.split("\\."); String[] v2 = version2.split("\\."); int len = v1.length<v2.length ? v1.length : v2.length; int count = 0; for(int i=0; i<len; i++) { if(Integer.parseInt(v1[i]) < Integer.parseInt(v2[i])) { return -1; } else if(Integer.parseInt(v1[i]) > Integer.parseInt(v2[i])) { return 1; } else { count ++; } } if(v1.length > v2.length) { for(int i=len; i<v1.length; i++) { if(Integer.parseInt(v1[i])!=0) { return 1; } } return 0; } else if(v1.length < v2.length) { for(int i=len; i<v2.length; i++) { if(Integer.parseInt(v2[i])!=0) { return -1; } } return 0; } else { return 0; } } }
