How come the time complexity of Binary Search is log n

WebLogarithms are the inverse of exponentials, which grow very rapidly, so that if \log_2 n = x log2 n = x, then n = 2^x n = 2x. For example, because \log_2 128 = 7 log2128 = 7, we know that 2^7 = 128 27 = 128. That makes it easy to calculate the runtime of a binary search algorithm on an n n that's exactly a power of 2.

Saying that f (n)∈ Θ (g (n)) means that f (n) has exactly the same order of growth as g (n). Basically, Big Theta is the intersection of Big O and Big Omega. Here are two simple definitions for Big Theta based on that fact:

WebHowever, as a matter of practice, we often write that binary search takes \Theta (\log_2 n) Θ(log2n) time because computer scientists like to think in powers of 2. There is an order to the functions that we often see when we analyze algorithms using asymptotic notation. WebIn this case, namely binary search on a sorted array, you can see that: (a) binary search takes at most [ log n + 1] steps; (b) there are inputs that actually force this many steps. So if T ( n) is the running time on a worst-case input for binary search, you can say that T …

WebI usually define them as follows: Let t ( x) be the number of steps taken by an algorithm A on input x. Let T ( n) be the worst-case running time complexity of A. T ( n) = m a x ( t ( x)) where max is over all inputs x of size n. Then T ( n) ∈ O ( g ( n)) if for every input of size n, A takes at most c ⋅ g ( n) steps. Moreover, WebFeb 14, 2024 · Binary Search Tree Delete Algorithm Complexity Time Complexity Average Case On average-case, the time complexity of deleting a node from a BST is of the order of height of the binary search tree.
