Plz answer question 7 only in 20 mints it's very urgent plzzzzz When describing an algorithm, do not forget to analyze its running time and explain why the algorithm is correct
5.
Is g(n)= O(f(n))? Why?
If f(n) = 1gn0.0000001 and g(n) = (logloglogn)3,000,000. Is f(n) = O(g(n)) or g(n) = O(f(n))?
6
Why?
f(n)=0.000000001, g(n) = logn¹,000,000
7.
Show that T(n) = n³ + 20n + 1 is not O(n²)
