Assume when encrypting $3$-bit plaintext with a block cipher with key $\text{K},$ the following ciphertext is obtained:
$$\begin{array}{|c|c|}
\hline \text{Plaintext} & \text{Ciphertext} \\
\hline 000 & 110 \\
\hline 001 & 001 \\
\hline 010 & 111 \\
\hline 011 & 010 \\
\hline 100 & 000 \\
\hline 101 & 011 \\
\hline 110 & 101 \\
\hline 111 & 100 \\
\hline
\end{array}$$
The following ciphertext was encrypted with the above cipher with key $\mathrm{K}$ in counter mode (with initial counter value $=0):$
$\text{C}=100110000$
What was the plaintext?
