啊后天就ddl了还叫我去喝酒，让我小酌我哪能不去。

我自己的代码：

#include<stdio.h>
#include<stdlib.h>

typedef struct
{
	int data[100];
	int last;
}list;

int delet(list* L3, list* L);
int search(list* L1, list* L2, list* L);

int main()
{
	list* L = (list*)malloc(sizeof(list));
	int m , n, p;
	list* A = (list*)malloc(sizeof(list));
	list* B = (list*)malloc(sizeof(list));
	list* C = (list*)malloc(sizeof(list));
	A->last = 0;
	B->last = 0;
	C->last = 0;
	L->last = 0;
	scanf("%d %d %d", &m, &n, &p);
	for (int i = 0; i < m; i++)
	{
		scanf("%d", &A->data[i]);
		A->last++;
	}
	for (int i = 0; i < n; i++)
	{
		scanf("%d", &B->data[i]);
		B->last++;
	}
	for (int i = 0; i < p; i++)
	{
		scanf("%d", &C->data[i]);
		C->last++;
	}
	search(B, C, L);
	delet(A, L);
	for (int i = 0; i < (A->last)-1; i++)
	{
		printf("%d ", A->data[i]);
	}
	printf("%d", A->data[A->last]);
}

int search(list* L1,
