What is the result of performing binary search on a sorted array for an element not present in the array?

Step 1: Start with a sorted array and the element you want to find.
Step 2: Set two pointers: one at the beginning of the array (left) and one at the end (right).
Step 3: Calculate the middle index by using the formula: middle = (left + right) / 2.
Step 4: Check if the middle element is equal to the element you are searching for.
Step 5: If the middle element is equal to the target, return the index of the middle element.
Step 6: If the middle element is less than the target, move the left pointer to middle + 1.
Step 7: If the middle element is greater than the target, move the right pointer to middle - 1.
Step 8: Repeat steps 3 to 7 until the left pointer is greater than the right pointer.
Step 9: If the left pointer exceeds the right pointer, it means the element is not in the array.
Step 10: Return a sentinel value (like -1) to indicate that the element was not found.
