What are the differences between binary search and linear search?

What are the differences between binary search and linear search?

Binary search is faster and more efficient than linear search, but it requires a sorted array. Linear search works on unsorted arrays.

Can you explain how binary search works?

Sure! Binary search divides the search interval in half repeatedly. It starts with the middle element and eliminates half of the search space.

What is the time complexity of both algorithms?

Linear search has a time complexity of O(n), while binary search has a time complexity of O(log n), making binary search much faster for large datasets.

When should I use linear search instead of binary search?

Use linear search when dealing with small or unsorted datasets, as it’s simpler and doesn’t require sorting.
