As we go from to to pages in the phonebook, we need only tear the phonebook in half at most one or two more times. We can apply the same logic to searching for a value in an array of sorted numbers. First, check the value stored at the middle index of the array.

So, just as we tore off half the phone book, we can now disregard the entire left half of this array. Next, check the value stored at the middle index of what's left of the array. This time, we'll discard the right portion of what's left of the array.
We've found the value we were searching for! This algorithm takes log n steps in the worst case.
Learning to Rip a Phone Book in Half
When there are only 7 array indices to check, n might not seem all that much bigger than log n. But if we have a 4 billion indices, the difference certainly matters. In that case, linear search would take 4 billion steps in the worst case, while binary search would only take Note however, that these arrays were presorted. We'll next cover sorting algorithms like bubble sort, merge sort, insertion sort, selection sort, and quick sort that can be employed if you're not lucky enough to start out with a sorted dataset!
