Given a string queryIP, return "IPv4" if IP is a valid IPv4 address, "IPv6" if IP is a valid IPv6 address or "Neither" if IP is not a correct IP of any type.
A valid IPv4 address is an IP in the form "x1.x2.x3.x4" where 0 <= xi <= 255 and xi cannot contain leading zeros. For example, "192.168.1.1" and "192.168.1.0" are valid IPv4 addresses while "192.168.01.1", "192.168.1.00", and "192.168@1.1" are invalid IPv4 addresses.
A valid IPv6 address is an IP in the form "x1:x2:x3:x4:x5:x6:x7:x8" where:
1 <= xi.length <= 4xi is a hexadecimal string which may contain digits, lowercase English letter ('a' to 'f') and upper-case English letters ('A' to 'F').xi.For example, "2001:0db8:85a3:0000:0000:8a2e:0370:7334" and "2001:db8:85a3:0:0:8A2E:0370:7334" are valid IPv6 addresses, while "2001:0db8:85a3::8A2E:037j:7334" and "02001:0db8:85a3:0000:0000:8a2e:0370:7334" are invalid IPv6 addresses.
\n
Example 1:
\n\n\nInput: queryIP = "172.16.254.1"\nOutput: "IPv4"\nExplanation: This is a valid IPv4 address, return "IPv4".\n\n\n
Example 2:
\n\n\nInput: queryIP = "2001:0db8:85a3:0:0:8A2E:0370:7334"\nOutput: "IPv6"\nExplanation: This is a valid IPv6 address, return "IPv6".\n\n\n
Example 3:
\n\n\nInput: queryIP = "256.256.256.256"\nOutput: "Neither"\nExplanation: This is neither a IPv4 address nor a IPv6 address.\n\n\n
\n
Constraints:
\n\nqueryIP consists only of English letters, digits and the characters '.' and ':'.给定一个字符串 queryIP。如果是有效的 IPv4 地址，返回 \"IPv4\" ；如果是有效的 IPv6 地址，返回 \"IPv6\" ；如果不是上述类型的 IP 地址，返回 \"Neither\" 。
有效的IPv4地址 是 “x1.x2.x3.x4” 形式的IP地址。 其中 0 <= xi <= 255 且 xi 不能包含 前导零。例如: “192.168.1.1” 、 “192.168.1.0” 为有效IPv4地址， “192.168.01.1” 为无效IPv4地址; “192.168.1.00” 、 “192.168@1.1” 为无效IPv4地址。
一个有效的IPv6地址 是一个格式为“x1:x2:x3:x4:x5:x6:x7:x8” 的IP地址，其中:
1 <= xi.length <= 4xi 是一个 十六进制字符串 ，可以包含数字、小写英文字母( 'a' 到 'f' )和大写英文字母( 'A' 到 'F' )。xi 中允许前导零。例如 \"2001:0db8:85a3:0000:0000:8a2e:0370:7334\" 和 \"2001:db8:85a3:0:0:8A2E:0370:7334\" 是有效的 IPv6 地址，而 \"2001:0db8:85a3::8A2E:037j:7334\" 和 \"02001:0db8:85a3:0000:0000:8a2e:0370:7334\" 是无效的 IPv6 地址。
\n\n
示例 1：
\n\n\n输入：queryIP = \"172.16.254.1\"\n输出：\"IPv4\"\n解释：有效的 IPv4 地址，返回 \"IPv4\"\n\n\n
示例 2：
\n\n\n输入：queryIP = \"2001:0db8:85a3:0:0:8A2E:0370:7334\"\n输出：\"IPv6\"\n解释：有效的 IPv6 地址，返回 \"IPv6\"\n\n\n
示例 3：
\n\n\n输入：queryIP = \"256.256.256.256\"\n输出：\"Neither\"\n解释：既不是 IPv4 地址，又不是 IPv6 地址\n\n\n
\n\n
提示：
\n\nqueryIP 仅由英文字母，数字，字符 '.' 和 ':' 组成。\\u7248\\u672c\\uff1a \\u7f16\\u8bd1\\u65f6\\uff0c\\u5c06\\u4f1a\\u91c7\\u7528
