Given an integer array of size $N$, we want to check if the array is sorted (in either ascending or descending order). An algorithm solves this problem by making a single pass through the array and comparing each element of the array only with its adjacent elements. The worst-case time complexity of this algorithm is

A

both $O(N)$ and $\Omega(N)$

B

$O(N)$ but not $\Omega(N)$

C

$\Omega(N)$ but not $O(N)$

D

neither $O(N)$ nor $\Omega(N)$
