Leetcode: binary tree upside down

Oct. 22, 2017


It is so nice to get a friend's help to offer me to mock interview the algorithm "binary tree upside down". I spent around 100 minutes to work on this algorithm.

Here is the C# code I wrote in the mock interview on Oct. 21, 2017 from 8:00 pm - 9: 53 pm.

Plan to read the leetcode discussion on the algorithm, the link is here.
