我的代码：

#include <bits/stdc++.h>
using namespace std;

char a[1001][1001];
int vis[1001][1001];

int main()
{
	int t;
	cin >> t;
	while (t--)
	{
		int n, m, k;
		cin >> n >> m >> k;
		int x, y, d;
		cin >> x >> y >> d;
		for (int i = 1; i <= n; i++)
		{
			for (int j = 1; j <= m; j++)
			{
				cin >> a[i][j];
			}
		}
		vis[x][y]=1;
		for (int i = 1; i <= k; i++)
		{
			if (d==0)
			{
				if (y+1<=m&&a[x][y+1]!='x')
				{
					y++;
					vis[x][y]++;
				} 
				else d=(d+1)%4;
			}
			else if (d==1)
			{
				if (x+1<=n&&a[x+1][y]!='x')
				{
					x++;
					vis[x][y]++;
				} 
				else d=(d+1)%4;
			}
			else if (d==2)
			{
				if (y-1>=1&&a[x][y-1]!='x')
				{
					y--;
					vis[x][y]++;
				} 
				else d=(d+1)%4;	
			}
			else if (d==3)
			{
				if (x-1>=1&&a[x-1][y]!='x')
				{
					x--;
					vis[x][y]++;
				}
				else d=(d+1)%4;	
			}
		}
		int ans=0; 
		for (int i = 1; i <= n; i++)
		{
			for (int j = 1; j <= m; j++)
			{
				if (vis[i][j]!=0)
				{
					ans++;	
				} 
			}
		}
		cout << ans << endl;
	} 
	return 0;
}

样例过了，为什么不对呢QAQ

求调，thx
