GATE | GATE-CS-2017 (Set 2) | Question 17

Match the algorithms with their time complexities:

(A) P-> (iii), Q -> (iv), R -> (i), S -> (ii)
(B) P-> (iv), Q -> (iii), R -> (i), S -> (ii)
(C) P-> (iii), Q -> (iv), R -> (ii), S -> (i)
(D) P-> (iv), Q -> (iii), R -> (ii), S -> (i)

Answer: (C)
Explanation:

• Tower of Hanoi – Ɵ(2ⁿ)
• Heap sort worst case – Ɵ(n log n)
• Binary Search – Ɵ(log n)
• Addition of two nxn matrices – Ɵ (n²)

Therefore Option (C) is correct
