好的,以下是一份完整的QT代码来实现残缺棋盘覆盖问题的可视化:

```
在这个代码中,我们使用QT中的QGraphicsView和QGraphicsScene来实现可视化。我们先创建一个棋盘的图形项(Board),然后用一个名为cover的递归函数来实现残缺棋盘覆盖算法。在每个递归步骤中,我们要么将棋盘分成四个部分,要么在棋盘上放置一个L型骨牌。我们使用QT中的QGraphicsItem和QPainter来绘制棋盘和骨牌。
在主函数中,我们创建一个主窗口,并将QT视图(view)设置为主窗口的中央窗口。我们添加棋盘和骨牌,并调整视图的大小和位置,最后显示窗口。
希望这个代码能够帮助您实现残缺棋盘覆盖问题的QT可视化。
