Being a rockstar is the intersection of who you are and who you want to be.

You have to write a function named davasaan (division with all vowels a) which calculates integer division by 10.
The vowels " eiou " are disallowed as are the slash " / ", asterisk " * ", and period " . " characters.

We have one more rule for this univocalic challenge. This is a code golf mission and your main goal is to make your code as short as possible: 300 characters is the maximum allowable. The shorter your code, the more remarkable you are.
Note that your code can start/end with empty lines and commented lines, they are not considered for code length. Hence you can comment a bit your code.

Input: A non-negative number as an integer.

Output: The integer division ( //10 ) of the input as an integer.
