如何使用堆栈/队列来管理其余工作？
public void Fill(int[,] array, int x, int y, int newInt){ int initial = array[x,y]; Queue<Tuple<int,int>> queue = new Queue<Tuple<int,int>>(); queue.Push(new Tuple<int, int>(x, y)); while (queue.Any()) { Tuple<int, int> point = queue.Dequeue(); if (array[point.Value1, point.Value2] != initial) continue; array[point.Value1, point.Value2] = newInt; EnqueueIfMatches(array, queue, point.Value1 - 1, point.Value2, initial); EnqueueIfMatches(array, queue, point.Value1 + 1, point.Value2, initial); EnqueueIfMatches(array, queue, point.Value1, point.Value2 - 1, initial); EnqueueIfMatches(array, queue, point.Value1, point.Value2 + 1, initial); }}private void EnqueueIfMatches(int[,] array, Queue<Tuple<int, int>> queue, int x, int y, int initial){ if (x < 0 || x >= array.GetLength(0) || y < 0 || y >= array.GetLength(1)) return; if (array[x, y] == initial) queue.Enqueue(new Tuple<int, int>(x, y));}
