Python 语言程序设计（2017 年秋）

Suppose you are reading byte streams from any device, representing IP addresses. Your task is to convert a 32 characters long sequence of 1s and 0s (bits) to a dotted decimal format. A dotted decimal format for an IP address is form by grouping 8 bits at a time and converting the binary representation to decimal representation. Any 8 bits is a valid part of an IP address.

To convert binary numbers to decimal numbers remember that both are positional numerical systems, where the first 8 positions of the binary systems are:

$2^7$ $2^6$ $2^5$ $2^4$ $2^3$ $2^2$ $2^1$ $2^0$
$128$ $64$ $32$ $16$ $8$ $4$ $2$ $1$

输入格式

The input will have a number $N$ $(1 \leq N \leq 9)$ in its first line representing the number of streams to convert. $N$ lines will follow.

输出格式

The output must have $N$ lines with a doted decimal IP address. A dotted decimal IP address is formed by grouping 8 bit at the time and converting the binary representation to decimal representation.
