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 $\Omega(N)$

Which one of the following options is CORRECT?

A

$$T(n) = \Theta(n \log \log n)$$

B

$$T(n) = \Theta(n \log n)$$

C

Consider the following syntax-directed definition (SDD).

S → DHTU { S.val = D.val + H.val + T.val + U.val; }
D → “M” D1 { D.val = 5 + D1.val; }
D → ε { D.val = –5; }
H → “L” H1 { H.val = 5 * 10 + H1.val; }
H → ε { H.val = –10; }
T → “C” T1 { T.val = 5 * 100 + T1.val; }
T → ε { T.val = –5; }
U → “K” { U.val = 5; }
Given “MMLK” as the input, which one of the following options is the CORRECT value computed by the SDD (in the attribute S.val)?
A

45

B

50
