Question: In a binary search algorithm, what happens if the target is less than the middle element?

Options:

  1. Search the right half
  2. Search the left half
  3. Return the middle element
  4. End the search

Correct Answer: Search the left half

Solution:

If the target is less than the middle element, the search continues in the left half of the array.

Questions & Step-by-Step Solutions

In a binary search algorithm, what happens if the target is less than the middle element?
  • Step 1: Start with a sorted array and identify the middle element.
  • Step 2: Compare the target value with the middle element.
  • Step 3: If the target is less than the middle element, ignore the right half of the array.
  • Step 4: Focus on the left half of the array, which contains smaller values.
  • Step 5: Repeat the process by finding the new middle element in the left half.
  • Binary Search Algorithm – A search algorithm that finds the position of a target value within a sorted array by repeatedly dividing the search interval in half.
  • Comparison Operation – The process of comparing the target value with the middle element to determine the next search interval.
  • Search Space Reduction – The method of eliminating half of the search space based on the comparison result.
