How to use C # binary search algorithm

Most people do not understand the knowledge points of this article "how to use the C# binary search algorithm", so the editor summarizes the following contents, detailed contents, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "how to use the C# binary search algorithm" article.

1. Definition:

Half search, also known as binary search algorithm, binary search, is a search algorithm to find a specific element in an ordered array.

To calculate the index value that inserts the target value into the array. The first train of thought:

1. Insert the target number into the array first

two。 Sort

3. Return to index

2. Implementation code: public static int process4 (int [] arr, int low, int high, int key) {int mid = (low + high) / 2; if (low > high) return-1; else {if (arr [mid] = = key) return mid Else if (arr [mid] > key) return process4 (arr, low, mid-1, key); else return process4 (arr, mid + 1, high, key) }} the above is the content of this article on "how to use the C# binary search algorithm".
