int32-to-ipv4

int32 to IPv4

Take the following IPv4 address: 128.32.10.1

This address has 4 octets where each octet is a single byte (or 8 bits).

• 1st octet 128 has the binary representation: 10000000
• 2nd octet 32 has the binary representation: 00100000
• 3rd octet 10 has the binary representation: 00001010
• 4th octet 1 has the binary representation: 00000001

So 128.32.10.1 == 10000000.00100000.00001010.00000001

Because the above IP address has 32 bits, we can represent it as the unsigned 32-bit number: 2149583361

Complete the function that takes an unsigned 32-bit number and returns a string representation of its IPv4 address.

Examples

2149583361 ==> "128.32.10.1"
32         ==> "0.0.0.32"
0          ==> "0.0.0.0"
