13. In the following code, A is an array indexed from 0 whose elements are all positive integers, and n is the number of elements in A .
\begin{verbatim}
function foo(A,n) {
max = 0;
curr = 0;
for i from 1 to (n-1) {
if A[i] > A[i-1] {
curr = curr + 1;
if curr > max {
max = curr;
}
} else {
curr = 0;
}
}
return(max+1);
}
\end{verbatim}
If $A = [ 1,3,5,2,4,7,6,8 ]$, what will $f \circ \circ ( A , 8 )$ return?\\
(a) 2\\
(b) 3\\
(c) 4\\
(d) 5\\
