给定两棵树T1和T2.如果T1可以通过若干次左右孩子互换就变成T2,则我们称两棵树是“同构”的. 例如图1给出的两棵树就是同构的,因为我们把其中一棵树的结点A.B.G的左右孩子互换后,就得到另外一棵树. 而图2就不是同构的. 图1 图2 现给定两棵树,请你判断它们是否是同构的. 输入格式: 输入给出2棵二叉树树的信息.对于每棵树,首先在一行中给出一个非负整数N (≤10),即该树的结点数(此时假设 结点从0到 N -1 编号):随后N行,第i行对应编号第i个结点,给出该结点中存储的1个英文大写字…

1021 Deepest Root (25 分)   A graph which is connected and acyclic can be considered a tree. The height of the tree depends on the selected root. Now you are supposed to find the root that results in a highest tree. Such a root is called the deepest r…
