What is the definition of overflow in binary?

1 answer:

4 0

Overflow occurs when the magnitude of a number exceeds the range allowed by the size of the bit field. The sum of two identically-signed numbers may very well exceed the range of the bit field of those two numbers, and so in this case overflow is a possibility.

Suppose that, even unrealistically, we are to search a list of 700 million items using Binary Search, Recursive (Algorithm 2.1).

Explanation:

Since we are talking about binary search, let's assume that the items are sorted according to some criteria.

Time complexity of binary search is O(logN) in worst case, best case and average case as well. That means it can search for an item in Log N time where N is size of the input. Here problem talks about the item not getting found. So, this is a worst case scenario. Even in this case, binary search runs in O(logN) time.

N = 700000000.

So, number of comparisions can be log(N) = 29.3 = 29.

So, in the worst case it does comparisions 29 times

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

int intgVal; double dblVal; char chrVal; String strVal;

System.out.print("Enter integer: ");

System.out.print("Enter double: ");

dblVal = input.nextDouble();

System.out.print("Enter character: ");

chrVal = input.next().charAt(0);

input.nextLine();

System.out.print("Enter string: ");

strVal = input.nextLine();

System.out.println(intgVal+" "+dblVal+" "+chrVal+" "+strVal);

System.out.println(strVal+" "+chrVal+" "+dblVal+" "+intgVal);

int IntValue = (int) dblVal;

System.out.print("Cast to an integer: "+IntValue);

}
