System.out.println("Item not found!");
WebThe key idea is that when binary search makes an incorrect guess, the portion of the array that contains reasonable guesses is reduced by at least half. If the reasonable portion had 32 elements, then an incorrect guess cuts it down to have at most 16. Binary search halves the size of the reasonable portion upon every incorrect guess. WebDrawbacks of Binary search. Binary search works only on sorted data. Recursion in Binary Search. The concept of recursion is to call the same function repeatedly within itself. There is a condition when this recursion stops. At each step of Binary Search, we reduce the potential size of the array by half where the target element can be found.
