Questions & Step-by-Step Solutions

What is a common searching algorithm used in applications with sorted data?
  • Step 1: Understand that a searching algorithm is a method used to find a specific item in a list or array.
  • Step 2: Know that a sorted data means the items are arranged in a specific order, like from smallest to largest.
  • Step 3: Learn about binary search, which is a method to find an item in sorted data.
  • Step 4: In binary search, you start by looking at the middle item of the sorted list.
  • Step 5: If the middle item is the one you are looking for, you are done.
  • Step 6: If the middle item is less than the item you want, you only need to search the right half of the list.
  • Step 7: If the middle item is greater than the item you want, you only need to search the left half of the list.
  • Step 8: Repeat this process of checking the middle item and narrowing down the search until you find the item or determine it is not in the list.
