Binary Search

This problem involves searching for a given value in a sorted array of integers. If the value is found, the index of the target value is returned; if not, -1 is returned.


Given a sorted array of integers and a target value, return the index of the target value if found, or -1 if not found.
Example input: [1, 3, 5, 7, 9], 5
Example output: 2
