Understanding Linear Search
Linear search is a straightforward algorithm that checks each element in a list one by one until it finds the target or reaches the end. It doesn’t require the data to be sorted, making it suitable for small or unsorted datasets.

How Linear Search Works
In linear search, the algorithm starts from the first element and compares it with the target value. If a match is found, it returns the index. If not, it proceeds to the next item, continuing until the target is found or the list ends linear search vs binary search.

What is Binary Search
Binary search is a more efficient algorithm but requires the data to be sorted. It works by repeatedly dividing the search interval in half. If the middle element is the target, the search ends. If not, the algorithm decides which half to continue searching in.

Speed Comparison Between the Two
Linear search has a time complexity of O(n), meaning the time it takes increases linearly with the number of items. Binary search has a time complexity of O(log n), making it significantly faster for large sorted datasets.

When to Use Linear Search
Linear search is useful when working with small datasets or when the data isn’t sorted. It’s easy to implement and doesn’t need any preprocessing of data.

When to Use Binary Search
Binary search should be used when dealing with large, sorted datasets. Its efficiency makes it ideal for quick lookups, such as in search engines or sorted records.
