#include <stdio.h>

int main()
{
	int arr[50] = { 0 };
	int i = 0;//i和j利用双下标达到删除指定数字的效果
	int j = 0;
	int n = 0;
	int x = 0;
    int count=0;//用于记录共删除数字的个数，避免数组中出现多次相同数字
	scanf("%d", &n);
	for ( i = 0; i < n; i++)
	{
		scanf("%d", &arr[i]);
	}
	scanf("%d", &x);
	for ( i = 0; i < n; i++)

	}

	for (j = 0; j < n-count; j++)

	return 0;
