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:
| $2^7$ | $2^6$ | $2^5$ | $2^4$ | $2^3$ | $2^2$ | $2^1$ | $2^0$ |
|---|---|---|---|---|---|---|---|
| $128$ | $64$ | $32$ | $16$ | $8$ | $4$ | $2$ | $1$ |
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.
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.
