Answer:
B. (n2) * n.
Step-by-step explanation:
The highest complexity is (n2)*n because on solving it will come out to be n³.So the growth rate is of cubical order which is the highest among the options.
(n) * 2n is of the order of square.On solving it will be 2n².
n² is also of the order of square.
nlogn complexity is less than n² but greater than n.
3n is of linear complexity.It has the lowest complexity among the options.
