558. 四叉树交集
题目解读:
存在两个n * n 的二进制矩阵- quadTree1 、quadTree2(二进制矩阵中的所有元素不是 0 就是 1 )。
返回一个表示 n * n 二进制矩阵的四叉树,它是 quadTree1 和 quadTree2 所表示的两个二进制矩阵进行 按位逻辑或运算 || 的结果。

注意:
四叉树数据结构中,每个内部节点只有四个子节点。此外,每个节点都有两个属性:
val:储存叶子结点所代表的区域的值。1 对应 True,0 对应 False;
isLeaf: 当这个节点是一个叶子结点时为 True,如果它有 4 个子节点则为 False 。
class Node {
public boolean val;
