5.1.9 Symmetric Tree这个题目描述是不是错了 #29

Closed aCayF closed 10 years ago

aCayF commented 10 years ago

原题描述是 Given a binary tree, check whether it is a mirror of itself (ie, symmetric around its center).

For example, this binary tree is symmetric: 1 / \ 2 2 / \ / \ 3 4 4 3

But the following is not: 1 / \ 2 2 \ \ 3 3
