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. Multiplying 2, 9 times (2^9) gives 512. But 2^9 < 600. 2^10 = 1024. 1024 > 600.
