Questions & Step-by-Step Solutions
How does binary search determine which half of the array to search next?
Step 1: Start with a sorted array and a target value that you want to find.
Step 2: Find the middle element of the array.
Step 3: Compare the middle element with the target value.
Step 4: If the middle element is equal to the target, you have found the target.
Step 5: If the middle element is less than the target, discard the left half of the array and focus on the right half.
Step 6: If the middle element is greater than the target, discard the right half of the array and focus on the left half.
Step 7: Repeat steps 2 to 6 until you find the target or the search space is empty.
Binary Search Mechanism – Binary search works by repeatedly dividing the search interval in half, comparing the target value to the middle element of the current interval.
