第一种:依次与有序数组中的每个数进行比较,然后找到位置之后,定义一个新的数组,该信数组的长度加一,再使用system.arraycopy将于数组copy到新数组!import java.util.Arrays; import java.util.Scanner; public class Sort { public static void main(String[] args) { Scanner in = new Scanner(System.in); int nums[] = new int…
Given an array of integers nums sorted in ascending order, find the starting and ending position of a given targetvalue.Your algorithm's runtime complexity must be in the order of O(log n). If the target is not found in the array, return [-1, -1]. Ex…
