数组：

//顶级垃圾程序 
#include <bits/stdc++.h>
using namespace std;

int n, x, y;
int arr[101];
int main(){
	cin >> n;
	for (int i = 0; i < n; i++) cin >> arr[i];
	cin >> x >> y;
	x -= 1;
	for (int i = n - 1; i >= x; i--){
		int temp = arr[i];
		arr[i + 1] = temp; 
	}
	arr[x] = y;
	for (int i = 0; i < n + 1; i++) cout << arr[i] << ' ';
	return 0;
