What is the return value of the following recursive algorithm when the input arguments are $A=[0,0,1,0,0,1,0,1]$ and

pos$=7?$

function $,$ pos $)$

if $(pos<mi\; id="EditorElement\_70258"></mi><mi\; id="EditorElement\_70260">)</mi>$

return $$

if $($pos$==$length $(A)-1$ or pos$=$e or $A[pos-1]==1$ or $A[pos+1]==1)$

return $,$ pos $-1$
