Problem Description

Tarjen has recently been learning Japanese. In Japanese, the pronunciations of the numbers $1$ to $9$ are as follows:

$$\def\arraystretch{1.5} \begin{array}{|c|c|} \hline \textbf{Number} & \textbf{Japanese Pronunciation} \\ \hline 1 & \verb!ichi! \\ \hline 2 & \verb!ni! \\ \hline 3 & \verb!san! \\ \hline 4 & \verb!yon! \\ \hline 5 & \verb!go! \\ \hline 6 & \verb!roku! \\ \hline 7 & \verb!nana! \\ \hline 8 & \verb!hachi! \\ \hline 9 & \verb!kyuu! \\ \hline \end{array}$$

To read a multi-digit number, you just concatenate the Japanese pronunciations of each digit from left to right. For example, $15$ is read as ichigo, and $893$ is read as hachikyuusan.

Tarjen's favorite number is $72$. Now he wants to test you: what is the Japanese pronunciation of $72$?
