Introduction
It is my favorite weekly contest 136. But I had hard time to manage my performance in the contest. I only solved second algorithm.
Performance review
I first spent 10 minutes to read the third algorithm. It took me more than ten minutes to understand the problem. I thought about the solution first.
I moved to second algorithm and I read the problem statement, I understood how to write a solution.
I moved to the first algorithm and try to understand the problem. It is an easy problem, but I do not know who designed the problem. I do not know what facing north - G implies. It took me over 10 to 15 minutes to try to figure out the problem statement. There are a few places confusing.
The first 30 minutes I spent time to read the first three problems. Next 40 minutes I spent time to write a solution for the third algorithm. I just could not believe that I did spend forty minutes.
Last 10 minutes I came out dynamic programming solution, but I ran out of time to write code.
