What is the result of performing binary search on an array with duplicate values?
Step 1: Understand what binary search is. It is a method to find a target value in a sorted array by repeatedly dividing the search interval in half.
Step 2: Know that binary search starts by looking at the middle element of the array.
Step 3: If the middle element is equal to the target value, the search is successful. However, there may be other occurrences of the target value in the array.
Step 4: If the middle element is less than the target, the search continues in the right half of the array.
Step 5: If the middle element is greater than the target, the search continues in the left half of the array.
Step 6: When duplicates are present, the binary search can return any one of the occurrences of the target value, depending on how the search is implemented.
