Binary search is named for its use of the binary number system. It operates by repeatedly dividing the search interval in half. This efficient method eliminates half of the potential match area with each step, ensuring a quicker find within a sorted array compared to a linear search.

FAQs & Answers

  1. What is binary search? Binary search is an efficient algorithm for finding an item in a sorted list by repeatedly dividing the search interval in half.
  2. How does binary search differ from linear search? Unlike linear search which checks each element one by one, binary search narrows down possible locations by half with each step, making it much faster for sorted data.
  3. In what scenarios is binary search used? Binary search is typically used in scenarios requiring quick search time through sorted datasets, such as databases and software applications.
  4. What are the disadvantages of binary search? Binary search requires the dataset to be sorted beforehand, which can be a drawback if sorting takes significant time or resources.
