Introduction


It is my favorite weekly contest 120. I solved first two algorithms, but I could not solve the third algorithm related to tree algorithm.


My performance


Here is my ranking.

Here are two algorithms I wrote in the contest.
977 Squares of a sorted array, here is my discuss link.
978 Longest turbulent subarray, here is my discuss link.

The algorithm I wrote for the third algorithm does not work. The design has an issue.

After the contest, I wrote the third and fourth algorithms.
979 Distribute coins in binary tree, here is my code written in C#.
980 Unique paths III, here is my code
