Binary Search Algorithm Explanation
This article explains the binary search algorithm for locating a target element in a sorted array, describing its midpoint‑starting process, halving of the search range, termination conditions, and includes a simple example with its output.
Binary search is a search algorithm for finding a specific element in a sorted array.
The search starts at the middle element; if it matches the target, the search ends. If the target is greater or smaller, the algorithm continues in the half of the array that is greater or smaller, again starting from the middle, and repeats until the element is found or the subarray becomes empty.
Each comparison reduces the search range by half.
Example:
元素在数组中的索引为 3
- END -
