思路：
需要两个数组，一个保存原始数据

import java.util.Scanner;

public class Main {
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int n = sc.nextInt();
		int shop[] = new int[n];//保存原始数据
		int store[] = new int[n];
		for(int i=0;i<n;i++) {
			shop[i] = sc.nextInt();
		}
		store[0] = (shop[0]+shop[1])/2;
		store[n-1] = (shop[n-2]+shop[n-1])/2;
		for(int j=1;j<n-1;j++) {
			store[j] = (shop[j-1]+shop[j]+shop[j+1])/3;
		}
		sc.close();
		for(int k=0;k<n;k++) {
			System.out.print(store[k] + " ");
		}
	}

}
