cin>>m>>n>>k>>s;

char arr[100][100];

for(int i=0;i<m;i++)
{
	for(int j=0;j<n;j++)
	{
		cin>>arr[i][j];
	}
}
for(int i=0;i<m;i++)
{
	for(int j=0;j<n;j++)
	{
		if(arr[i][j]=='#')
		{
			m++;
		}
		if(arr[i][j]=='.')
		{
			s=s-2;
			s--;
		}
			
		if(arr[i][j]=='*')
			{
				s=s+5;
				s--;
			}
		if(arr[i][j]<0)
			break;
	}
}
if(s>=k)
{
	cout<<"Yes"<<endl<<s<<endl;

cout<<"No"<<endl;
