Binary Search Using Recursion
Binary search is faster than linear search. It works only on a
sorted set of elements.
List 5 6 9 19 23 32 45
Element to be searched 32
low mid high
5 6 9 19 23 32 45
Step 1: First, compare x with the middle element.
Step 2: If x matches with the middle element, then
you have to return the mid index.
if 19 == 32
Step 3: Else, If x is greater than the mid element,
then x can only lie in the right side half array after
the mid element. Hence you recur the right half.
New List - 23 32 45
Step 4: Else, if (x is smaller) then recur for the left half.
Step 5: Repeat the process till element is found or list ends.
low mid high
23 32 45
Binary Search
1. Regular Way ( with loops and conditional statements )
2. Using Recursion
3. Using binarysearch method of Array class
4. Using binarysearch method of Collection class
