Here is a Turing Machine. It always starts to the left of a single cluster of input, in state A$,$ on a blank $($#$)$ space. The cluster contains only $1$s and Os with infinite #s on either side. The cluster can be as short as just one character. The cluster must contain at least one $1.$

Note: This is the same machine as the one in the previous question.

What is the best description of what this machine does?

$\backslash$table$[[$STATE$,$SYMBOL,NEW SYMBOL,MOVE,NEW STATE$],[A,$#$,$#$,R,$A$],[$A$,0,0,R,B$
