Q49

Suppose $c = \langle c[0], \dots, c[k-1]\rangle$ is an array of length $k$, where all the entries are from the set $\{0, 1\}$. For any positive integers $a \text{ and } n$, consider the following pseudocode. DOSOMETHING (c, a, n) z ← 1 for i ← 0 to k-1 do z ← z² mod n if c[i]=1 then z ← (z × a) mod n return z If $k=4, c = \langle 1, 0, 1, 1 \rangle , a = 2, \text{ and } n=8$, then the output of DOSOMETHING(c, a, n) is _______.
