# Task
An IP address contains four numbers(0-255) and separated by dots. It can be converted to a number by this way:
Given a string `s` represents a number or an IP address. Your task is to convert it to another representation(`number to IP address` or `IP address to number`).
You can assume that all inputs are valid.
# Example
Example IP address: `10.0.3.193`
Convert each number to a 8-bit binary string
(may needs to pad leading zeros to the left side):
```
10  -->  00001010
0   -->  00000000
3   -->  00000011
193 -->  11000001
```
Combine these four strings: `00001010 00000000 00000011 11000001` and then convert them to a decimal number:
`167773121`
# Input/Output
`[input]` string `s`
A number or IP address in string format.
`[output]` a string
A converted number or IP address in string format.
# Example
For `s = "10.0.3.193"`, the output should be `"167773121"`.
For `s = "167969729"`, the output should be `"10.3.3.193"`.
