题解 | #比较版本号#

前面赞最多的好像是错的，这里贴一下菜鸡自己的代码：

    public static int compare(String version1, String version2) {
        String[] split1 = version1.split("[.]");
        String[] split2 = version2.split("[.]");
        int len = Math.min(split1.length, split2.length);
        for (int i = 0; i < len; i++) {
            if (Integer.parseInt(split1[i]) > Integer.parseInt(split2[i])) return 1;
            else if (Integer.parseInt(split1[i]) < Integer.parseInt(split2[i])) return -1;
        }
        String[] split3 = split1.length>split2.length?split1:split2;
        for (int i = len;i<split3.length;i++){
            if (Integer.parseInt(split3[i])!=0) return split1.length>split2.length?1:-1;
        }
        return 0;
    }
