If a binary search algorithm returns -1, what does it indicate?

Step 1: Understand what a binary search algorithm does. It looks for a specific element in a sorted array.
Step 2: When you use the binary search, you provide it with the element you want to find.
Step 3: If the algorithm finds the element, it returns the index (position) of that element in the array.
Step 4: If the algorithm does not find the element in the array, it returns -1.
Step 5: Therefore, a return value of -1 means that the element you were searching for is not present in the array.

Binary Search Algorithm – A search algorithm that finds the position of a target value within a sorted array.
Return Values – Understanding what different return values signify in the context of algorithms.
