468. Validate IP Address Medium

1/**
2 * [468] Validate IP Address
3 *
4 * 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.
5 * 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 "[email protected]" are invalid IPv4 addresses.
6 * A valid IPv6 address is an IP in the form "x1:x2:x3:x4:x5:x6:x7:x8" where:
7 * 
8 * 	1 <= xi.length <= 4
9 * 	xi is a hexadecimal string which may contain digits, lowercase English letter ('a' to 'f') and upper-case English letters ('A' to 'F').
10 * 	Leading zeros are allowed in xi.
11 * 
12 * 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.
13 *  
14 * Example 1:
15 * 
16 * Input: queryIP = "172.16.254.1"
17 * Output: "IPv4"
18 * Explanation: This is a valid IPv4 address, return "IPv4".
19 * 
20 * Example 2:
21 * 
22 * Input: queryIP = "2001:0db8:85a3:0:0:8A2E:0370:7334"
23 * Output: "IPv6"
24 * Explanation: This is a valid IPv6 address, return "IPv6".
25 * 
26 * Example 3:
27 * 
28 * Input: queryIP = "256.256.256.256"
29 * Output: "Neither"
30 * Explanation: This is neither a IPv4 address nor a IPv6 address.
31 * 
32 *  
33 * Constraints:
34 * 
35 * 	queryIP consists only of English letters, digits and the characters '.' and ':'.
