Questions & Step-by-Step Solutions

Which of the following is a limitation of binary search?
  • Step 1: Understand what binary search is. It is a method used to find a specific value in a list of sorted numbers.
  • Step 2: Know that binary search works by repeatedly dividing the list in half to narrow down the possible location of the value.
  • Step 3: Recognize that for binary search to work correctly, the list must be sorted in a specific order (either ascending or descending).
  • Step 4: Identify the limitation: If the data is not sorted, binary search cannot be used effectively, and it may give incorrect results.
