Binary search is a method to find the particular item in the sorted array. In each step, the algorithm divides the array equally and match the middle item. If the key match, return the index. If the key is less than the middle element, search left subarray. Else search right subarray.
Binary search uses divide and conquers strategy to search the item from the sorted array. The binary search eliminates half of the elements for each iteration. It requires sorted array and will not work for the un-sorted array like linear search.
The binary search algorithm can be implemented using an iterative method or recursive method. Write a program to implement Binary search.
Before Sort: [12, 55, 45, 11, 23, 20, 17, 24, 9] After Sort: [9, 11, 12, 17, 20, 23, 24, 45, 55] Found in 2 Position!
