Q50

A set $X$ can be represented by an array $x[n]$ as follows: $x\left [ i \right ]=\begin {cases} 1 & \text{if } i \in X \\ 0 & \text{otherwise} \end{cases}$ Consider the following algorithm in which $x$, $y$, and $z$ are Boolean arrays of size $n$: algorithm zzz(x[], y[], z[]) { int i; for(i=0; i<n; ++i) z[i] = (x[i] ∧ ~y[i]) ∨ (~x[i] ∧ y[i]); } The set $Z$ computed by the algorithm is:
