模拟算法，大样例全过但TLE，最后30Pts,求优化

#include <iostream>
#include <cstdio>
using namespace std;
bool a[200005];

int main() {
	//freopen("revflip4.in", "r", stdin);
	//freopen("revflip4.out", "w", stdout);
	int n;
	cin >> n;
	for (int i = 1; i <= n; i++) {
		int k;
		cin >> k;
		if (k == 1)
			a[i] = true;
		if (k == 0)
			a[i] = false;
		for (int j = 1; j <= i / 2; j++) {
			swap(a[j], a[i + 1 - j]);
			a[j] = !a[j];
			a[i + 1 - j] = !a[i + 1 - j];
		}

	}
	for (int i = 1; i <= n; i++) {
