Key Requirements for Binary Search

Sorted Data: Binary search only works on data that is already sorted. If the data is not sorted, you’ll need to sort it first, which adds to the overall time complexity.

Random Access: Binary search requires the ability to access any element in the list or array directly (constant time access), which is typical for arrays and lists in most programming languages.

In Summary:
Binary search is a powerful and efficient algorithm for searching within sorted data. Its logarithmic time complexity makes it significantly faster than linear search for large datasets. Understanding binary search is fundamental in computer science and has wide applications in various algorithms and data structures.
