WebFor operating binary search, the input array needs to be sorted. So, the idea is, we can start with the middle element. If the searching element is less than the middle element, there’s no need to check the elements on the right half of the middle element, i.e., we can skip the elements larger than middle element. WebMar 9, 2016 · 7. You can't. "Binary search" checks if the value is in left or right side, comparing when it's lesser or bigger than the central item. Array: 2 6 8 5 34 1 12. Suppose that you want to find '1', so in first iteration the method will compare '1' with the currently central element (in this case '5'). The method would say: "As 1 is lesser than 5 ...
