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. WebWith binary search, every wrong guess eliminates half the possibilities at once. A binary search algorithm starts in the middle of a sorted list and repeatedly eliminates half the list until either the desired value is found or all elements have been eliminated.
