Binary Search Algorithm Overview

What is the primary requirement for using the Binary Search algorithm?

Binary Search can be applied to any type of data structure without requiring a sorted order.

What is the main advantage of using Binary Search over Linear Search?

In Binary Search, the search space is divided into ____ halves with each step.

Match the following terms with their definitions:

What is the example target value in the coding problem mentioned?

The Binary Search algorithm can find values in an unsorted array.

In a Binary Search approach, how does the search space change with each iteration?

Binary Search Algorithm

Binary search is a more efficient search algorithm than linear search, especially for large sorted datasets.
It leverages the sorted nature of the data to significantly reduce the search space.
Binary search works by repeatedly dividing the search interval in half.
Only applicable to sorted data.

Real-Life Example

Imagine searching for a word ("raj") in a dictionary (sorted alphabetically).
Method 1 (Linear Search): Check every page sequentially.
Method 2 (Binary Search):
- Open the dictionary roughly in the middle.
- Check the words on the left page.
- If "raj" comes before the words on the left page, search only in the left half.
- Repeat this process in each half, shrinking the search space each time until the word is located.

Key Characteristics

Requires a sorted search space (e.g., an array, a dictionary).
Divides the search space into two equal parts at each step.
Shrinks the search space based on which half potentially contains the target value.

Coding Example

Given a sorted array {3, 4, 6, 7, 9, 12, 16, 17} and a target value of 6.
Binary search efficiently finds the target within the array, without needing to check every element.
