算法训练 区间k大数查询

Problem:

AcCode: 

import java.util.Arrays;
import java.util.Scanner;

public class Main{
	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
		int n = in.nextInt();
		int[] nums = new int[n];
		for (int i = 0; i < nums.length; i++) {
			nums[i] = in.nextInt();
		}
		int m = in.nextInt();
		while(m!=0) {
			int l = in.nextInt();
			int r = in.nextInt();
			int k = in.nextInt();
			int[] temp = new int[r-l+1];
			temp = Arrays.copyOfRange(nums, l-1, r);
			Arrays.sort(temp);
			System.out.println(temp[temp.length-k]);
			m--;
		}
	}
}
