Questions & Step-by-Step Solutions

What is the result of performing a binary search on the array [2, 4, 6, 8, 10] for the value 5?
  • Step 1: Start with the array [2, 4, 6, 8, 10].
  • Step 2: Identify the value we are searching for, which is 5.
  • Step 3: Find the middle index of the array. The array has 5 elements, so the middle index is 2 (0-based index).
  • Step 4: Check the value at the middle index (index 2). The value is 6.
  • Step 5: Compare the middle value (6) with the target value (5). Since 6 is greater than 5, we will search in the left half of the array.
  • Step 6: The left half of the array is [2, 4].
  • Step 7: Find the new middle index of the left half. The new middle index is 1 (0-based index).
  • Step 8: Check the value at the new middle index (index 1). The value is 4.
  • Step 9: Compare the new middle value (4) with the target value (5). Since 4 is less than 5, we will search in the right half of the left half.
  • Step 10: The right half of the left half is [6].
  • Step 11: Since there are no more elements to check, we conclude that the value 5 is not present in the array.
  • Step 12: The result of the binary search is 'Not found'.
