AC 46 个点，WA 11 个点，能否给组 Hack 数据？

Code：

#include <bits/stdc++.h>
using namespace std;
const int N = 400005;
int n, p[N], q[N];
char ans[N];

int main() {
	scanf("%d", &n);
	n <<= 1;
	for (int i = 1; i <= n; ++i) scanf("%d", &p[i]);
	for (int i = 1; i <= n; ++i) scanf("%d", &q[i]);
	for (int i = 1; i < n; ++i) {
		if (p[i] > p[i + 1]) {
			if (ans[p[i]] == ')' || ans[p[i + 1]] == '(') return printf("%d", -1), 0;
			ans[p[i]] = '(', ans[p[i + 1]] = ')';
		}
	}
	for (int i = 1; i < n; ++i) {
		if (q[i] < q[i + 1]) {
			if (ans[q[i]] == ')' || ans[q[i + 1]] == '(') return printf("%d", -1), 0;
			ans[q[i]] = '(', ans[q[i + 1]] = ')';
		}
	}
	for (int i = 1; i <= n; ++i) if (!ans[i]) return printf("%d", -1), 0;
	for (int i = 1; i <= n; ++i) printf("%c", ans[i]);
	return 0; 
}
