Answer :
The binary search algorithm will cut the portion of the array being searched in half each time the loop fails to locate the search value.
In order to execute a binary search, you must first:
- Start your search using the middle member in the entire array.
- Return an index of the search key if the value of the search key equals the item.
- Alternately, if the search key's value is smaller than the item in the interval's midpoint, limit the interval to its lower half.
- If not, restrict it to the upper half.
- Check the interval from the second point again until the value is discovered or it is empty.
The following two methods can be used to implement the binary search algorithm:
- Iterative Process
- Recursive Technique

The binary search algorithm:
A.is less efficient than the sequential search algorithm
B. will cut the portion of the array being searched in half each time the loop fails to locate the search value
C. will have a maximum number of comparisons equal to the number of elements in the array
D. will have an average of N/2 comparisons, where N is the number of elements in the array
An effective algorithm for breaking down a list of things is binary search. In order to reduce the number of potential spaces to just one, it operates by continuously dividing in half the section of the list that could contain the object.
Finding a particular item in an array is one of the most typical applications of binary search.
After just one comparison, we essentially discard half of the components.
1. Evaluate x against the middle element.
2. If x matches the middle element, the mid index is returned.
3.Else If x is greater than the middle element, it can only be after the mid element in the right half of the list. So, for the right half, we repeat.
4.If (x is less), repeat
