Question

Which is the lowest Complexity"

Answer 1

Answer:

E. 3n

Explanation:

Of the options given, 3n represents the lowest complexity = O(3n). Since O(constant * n) is the same as O(n) this represents linear complexity.

All other given options represent a complexity higher than linear complexity.

• (n) * 2n > O(n)

• (n2) * n > O(n)

• n^2 > O(n)

• nlogn > O(n)

This is because quadratic complexity and log-linear complexity are higher than linear.
