Problem I
basic
The programming language Ada has integer constants that look like this: 123, 8#123#, 16#abc#. These constants represent the integers $123$, $83$ (123 base $8$) and $2739$ (abc base $16$). More precisely, an integer may be a decimal integer given as a sequence of one or more digits less than $10$, or it may be an integer to some specific base, given as the base followed by a sequence of one or more digits less than the base enclosed by # symbols. Lower case letters from a through f are used as the digits representing $10$ through $15$. In Ada, the base, if specified, must be a sequence of decimal digits. For this problem, however, the base may be of any form described above so long as it represents an integer between $2$ and $16$ inclusive.
Input
The first line of input contains a positive integer $n \le 100$. $n$ lines follow. Input lines use ASCII characters $33$-$126$, and are between $1$ and $80$ characters in length.
Output
For each line of input, output a line “yes” if it is a valid integer constant according to the above rules; otherwise output a line containing “no”.
