Definition: "20090409_rmskawk" is a binary search algorithm in computer science.
Definition: Binary search (also called binary search tree) is an efficient searching method for data structures, particularly arrays or lists. It operates by repeatedly dividing half of the input into two halves and finding the place where the target value should be inserted to keep that element in its sorted position. The process continues until the entire array or list is traversed.
Binary search uses a binary tree as the base case since the smallest elements are always at the leaves, allowing for quick searches. In the worst-case scenario when the input is completely ordered and the target value is not already present in the tree (i.e., its position would be 0), this approach reduces to linear search.
In practice, binary search can achieve a factor of log n (or logarithmic time complexity) on average for searching values that are at least twice as long as their key.
