At one move it's allowed to rotate the alphabetic wheel one step clockwise or counterclockwise. Initially, static pointer points to letter '<span class="tex-font-style-tt">a</span>'.

Hint

 



To print the string from the first sample it would be optimal to perform the following sequence of rotations:

from 'a' to 'z' (1 rotation counterclockwise),
from 'z' to 'e' (5 clockwise rotations),
from 'e' to 'u' (10 rotations counterclockwise),
from 'u' to 's' (2 counterclockwise rotations).

In total, 1 + 5 + 10 + 2 = 18 rotations are required.
