To determine the efficiency of an algorithm the time factor is measured by:
(A) Counting micro seconds
(B) Counting number of key operations
(C) Counting number of statements
(D) Counting kilobytes of algorithm


Answer: (B)

Explanation: To determine the efficiency of an algorithm the time factor is measured by counting number of key operations. It is not measured by counting of statements because less no of statement does not mean that program is more efficient. Many times we have to write large code for better efficieny. We measure space complexity in kilobytes.
So, option (B) is correct.
