给晚安学长出的题，种个草

#include <iostream>
using namespace std;
const int N = 3e5 + 5;
int a[N];
int main()
{
	int t, n;
	cin >> t;
	while (t--)
	{
		cin >> n;
		for (int i = 1; i <= n; i++)
			cin >> a[i];
		int ls = 0, t = 0, res = 1;
		for (int i = 2; i <= n; i++)
		{
			if (a[i - 1] < a[i])
				ls = 1;
			else if (a[i - 1] > a[i])
				ls = -1;
			else
				continue;
			if (t != ls)
				res++;
			t = ls;
		}
		cout << res << endl;
	}
