Q: What will be the output of the binary search function if the target is not found?
Solution:
Typically, binary search returns -1 if the target value is not found in the array.
Steps: 4
Show Steps
Step 1: Understand that binary search is a method used to find a target value in a sorted array.
Step 2: If the target value is not present in the array, the binary search will continue to check until it has searched all possible positions.
Step 3: When the search is complete and the target value is not found, the function will return a specific value to indicate this.
Step 4: In most implementations of binary search, this specific value is -1, which means 'not found'.
