1. Introduction to Binary Search

Binary Search is a fast algorithm used for searching an item in a sorted array or a sorted list. It works by repeatedly dividing the search interval in half.

What is Binary Search?

Binary Search is a searching technique that compares the target value to the middle element of the sorted array. Depending on the result, it recursively searches the left or right half of the array.

Why use Binary Search?

Binary Search is significantly faster than linear search (sequential search) when dealing with large sorted arrays. Its time complexity is O(log n) which makes it highly efficient for searching large datasets.

When to use Binary Search?

Binary Search is best used with sorted arrays or lists, where the elements are already arranged in order. This allows the algorithm to quickly locate the target element by repeatedly dividing the search space in half.
