Question: Which of the following best describes the iterative approach to binary search?

Options:

Correct Answer: Uses a loop to narrow down the search

Solution:

The iterative approach uses a loop to continuously narrow down the search range until the target is found or the range is empty.

Which of the following best describes the iterative approach to binary search?

Step 1: Start with a sorted list of numbers and define the target number you want to find.
Step 2: Set two pointers: one at the beginning of the list (left) and one at the end of the list (right).
Step 3: While the left pointer is less than or equal to the right pointer, do the following:
Step 4: Calculate the middle index by taking the average of the left and right pointers.
Step 5: Check if the number at the middle index is equal to the target number.
Step 6: If it is equal, you have found the target and can return its index.
Step 7: If the target number is less than the number at the middle index, move the right pointer to the middle index - 1.
Step 8: If the target number is greater than the number at the middle index, move the left pointer to the middle index + 1.
Step 9: Repeat steps 3 to 8 until you find the target or the left pointer exceeds the right pointer.
Step 10: If the left pointer exceeds the right pointer, it means the target is not in the list.
