Questions & Step-by-Step Solutions

What happens if you apply binary search on a linked list?
  • Step 1: Understand what binary search is. It is a method to find an item in a sorted list by repeatedly dividing the search interval in half.
  • Step 2: Know that binary search requires random access to elements. This means you can quickly jump to the middle of the list.
  • Step 3: Recognize that a linked list is a data structure where each element points to the next one. You cannot jump directly to the middle element.
  • Step 4: Realize that because you cannot access the middle element directly, you cannot perform binary search on a linked list.
  • Step 5: Conclude that binary search is not suitable for linked lists, and other search methods like linear search should be used instead.
