Condition of Binary Search Algorithm

Binary Search only works under specific conditions. These conditions are important to ensure the algorithm’s success:

1. The Array Must Be Sorted:
   The array or list you are searching through must be sorted in either ascending or descending order. If the array is not sorted, binary search will not work properly, as it relies on this property to halve the search space.
2. Random Access:
   Binary Search is most effective on data structures that allow random access, such as arrays. This is because the algorithm directly calculates the middle index, which is efficient in arrays but can be slow in linked lists where accessing a middle element takes linear time.
3. Fixed Size:
   Binary Search is typically applied to static arrays, where the size of the array remains constant during the search. In dynamic data structures where elements are frequently added or removed, adjustments might be needed.
