我不完全了解您需要什么,但我认为这听起来像是一个很好且有趣的练习。我希望这是你想要的。=) 它没有完全按照我想要的方式编码。宁愿使用 bool[,] 数组,但不知道如何使该数组动态化,也不想为此编写自己的类,但也许我应该这样做。
但是,此解决方案应该有效。
private List<List<bool>> grid = new List<List<bool>>();
private int N = 4;
Random randomNumberGenerator = new Random();
private bool getRandomBoolean()
{
return this.randomNumberGenerator.Next(0, 2) == 1;
}
private void testProgram()
{
var containsTrue = coordinateContainsTrue(0, 10);
var total = getTrueCoordinatesInArea(14, 2);
var isTrue = coordinateIsTrue(15, 11);
}
private bool coordinateIsTrue(int x, int y)
{
expandGridOfNeeded(x, y);
return grid[x][y];
}
private bool coordinateContainsTrue(int x, int y)
{
expandGridOfNeeded(x, y);
for (int xTemp = 0; xTemp < x; xTemp++) // Loop columns
{
for (int yTemp = 0; yTemp < y; yTemp++) // Loop rows
{
if (grid[xTemp][yTemp])
return true; // Return true if any true was found
}
}
return false;
}
private int getTrueCoordinatesInArea(int x, int y)
{
expandGridOfNeeded(x, y);
var total = 0;
for (int xTemp = 0; xTemp < x; xTemp++) // Loop columns
{
for (int yTemp = 0; yTemp < y; yTemp++) // Loop rows
{
if (grid[xTemp][yTemp])
total++; // Increase count if true was found
}
}
return total;
}
private void expandGridOfNeeded(int x, int y)
{
if (x < 0 || y < 0)
return;
// Add needed columns
while (grid.Count <= x)
{
var column = new List<bool>();
// Only add rows if the others have rows
if (grid.Count > 0)
{
while (column.Count < grid[0].Count)
{
// Check if legal to add a true value, if it is then add random else add false
bool forceFalseValue = false;
for (int i = grid.Count - 1; i > grid.Count + N && forceFalseValue == false; i--)
{
forceFalseValue = grid[i][column.Count - 1];
}
column.Add(forceFalseValue ? false : getRandomBoolean());
}
}
grid.Add(column);
}
// Add needed rows
while (grid[0].Count <= y)
{
var counter = N;
foreach (var column in grid)
{
// Check if legal to add a true value, if it is then add random else add false
if (counter < N)
{
column.Add(false);
counter++;
}
else
{
var randomValue = getRandomBoolean();
if (randomValue)
counter = 0;
else
counter++;
column.Add(randomValue);
}
}
}
