数组元素的移动

#include<bits/stdc++.h>
using namespace std;
int n, m, u, o;
int main(){
	vector<int>a;
	cin >> n;
	for(int i = 0; i < n; i++){
		cin >> m;
		a.push_back(m);
	}
	cin >> u;
	o = a[u - 1];
	for(int i = u - 1;i < n - 1;i++){
		a[i] = a[i + 1];
		cout << a [i] << " ";
	}
		cout << o;
	return 0;
}
