Expert Solution

Introduction :-

NOTE :- Below i explain the answer in my own words by which you understand it well.

O(f(n2)) and (n2) are frequently misunderstood. The former indicates that the running time is quadratic at most, while the latter indicates that it is quadratic. "The running time of algorithm A is at least (n2)" was probably what you meant to say. This indicates that A runs slower or in quadratic time.

To put it another way, the arithmetic expression "The value of x is at least less than 10" is analogous to the statement in the question.
