OR-thodox Distinction

CodeChefRating 1658Open on judge ↗

You are given an integer sequence $A_1, A_2, \ldots, A_N$. For any pair of integers $(l, r)$ such that $1 \le l \le r \le N$, let's define $\mathrm{OR}(l, r)$ as $A_l \lor A_{l+1} \lor \ldots \lor A_r$. Here, $\lor$ is the bitwise OR operator. In total, there are $\frac{N(N+1)}{2}$ possible pairs $(l, r)$, i.e. $\frac{N(N+1)}{2}$ possible values of $\mathrm{OR}(l, r)$. Determine if all these va
