直接看代码

package com.lm.digui;

public class GuiBinSort {
public static void main(String[] args) {
int[] arr = {1, 2, 3, 5, 8};
System.out.println(guibinNumber(arr, 0, arr.length - 1, 5));
}

private static int guibinNumber(int[] arr, int low, int high, int keyvalue) {
if (low < high) {
int mid = (low + high) / 2;
if (keyvalue == arr[mid]) {
return mid;
} else if (keyvalue < arr[mid]) {
return guibinNumber(arr, low, mid - 1, keyvalue);
} else if (keyvalue > arr[mid]) {
return guibinNumber(arr, mid + 1, high, keyvalue);
}

}
return -1;
}

}
