List of top Computer Science Questions on Time Complexity asked in CUET (PG)

Consider a procedure LIST-SEARCH (L, K) finds the first element with key K in list L by simple linear search, returning a pointer to its element. Arrange the following according to correct order of execution.
• [A.] x = L.head
• [B.] while x $\neq$ NIL and x.key $\neq$ K
• [C.] return x
• [D.] x = x.next
Choose the correct answer from the options given below:

In a ______ linked list, the last node's link field points to the first node of the list.

Match List-I with List-II:
\[\begin{array}{|c|c|}\hline \textbf{List-I} & \textbf{List-II} \\ \hline (A)\ \text{Binary Search} & (I)\ T(n) = T(n/2) + c \\ \hline (B)\ \text{Merge Sort} & (II)\ T(n) = 2T(n/2) + \Theta(n) \\ \hline (C)\ \text{Quick Sort (worst case)} & (III)\ T(n) = T(n-1) + \Theta(n) \\ \hline (D)\ \text{Linear Search} & (IV)\ T(n) = T(n-1) + c \\ \hline \end{array}\] Choose the correct answer from the options given below:
