Binary Search Algorithm

Página 1

Binary Search

Binary Search starts by picking the middle element of the array. If it is larger than the item wanted, it removed the first half of the array. If it is smaller, it removes the second half. It will continue to do this until it finds the element wanted.

Advantages:

Fast - gets rid of half the array on just the first run

It can indicate where in the array the element is (near the beginning, towards the end)

Disadvantages

Harder to implement that linear search

Requires an already sorted (ascending order) array!
