WebThere are differrent ways to implement the binary search algorithm. For the following practice examples, we use the iterative binary search algorithm that is presented in the next section.. As is explained in the next section, this code implementation uses the formula midpoint = (first + last) DIV 2 to calculate the midpoint position. This means that: WebFor binary search, the total iterations required to find a number would be atmost log2 (total_array_size). So for an array of size 600 (assuming the array to be sorted) the easiest way to find is, calculate the total number of times 2 needs to be multiplied to get 600. …
