Binary Search Algorithm Explanation

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 -
