WebThe lower bound of the time complexity will be: On the other hand, instead of the ‘logn’ term, if we add an e term in the power of n, Where, e > 0. Because, if the power of n grows that will grow faster than the ‘logn’ term. By solving this recurrence, we can get the upper bound. Here, a = 6, b = 2 and d = 2+e.
