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. WebJun 22, 2024 · A simple approach is to do a linear search, i.e Start from the leftmost element of arr [] and one by one compare x with each element of arr [] If x matches with an element, return the index. If x doesn’t match with any of the elements, return -1. Example: Iterative Approach: Python def search (arr, x): for i in range(len(arr)): if arr [i] == x: list of minutemen
