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. WebHere's the pseudocode for binary search, modified for searching in an array. The inputs are the array, which we call array; the number n of elements in array; and target, the number being searched for. The output is the index in array of target: Let min = 0 and max = n-1. five finger death punch seasons change
