Graph
Explain the Binary Search algorithm
Find the middle value and compare it to the value we're searching for. If it's not equal, narrow the search to either the left or right half of the array, depending on whether the middle value is greater or less than the target. This process is repeated recursively until the target value is found or the search space is empty, indicating that the value is not in the array.
