Introduction
It is the weekly contest 116. I wrote the first two algorithms. And I like to spend a few minutes to document my experience.
weekly contest 116
Here is my performance.
Changes I made
This time I started to write the code directly on Leetcode.com. I tried to simplify the process, avoid debugging the code. I had to push myself think hard.
The first algorithm took me almost first 30 minutes to solve it. I did not read carefully about the problem statement, I solved one I practiced before; after I submitted and failed, I learned that the giving condition is different, N + 1 unique numbers, one unique number has N + 1 copy. So only one number has more than one copy.
The second algorithm I also worked on preprocessing carefully. I ran into so many issues and it took me almost 50 minutes. I need to learn how to expedite the process. I spent over 25 minutes to debug the code, and I found out that I failed so many edge cases. I submitted five times.
Good discussion about last algorithm is here. I spent over 5 minutes to look into the top player with a lot of competition experience, the leetcode profile is here.
Statistics
Q1 1939 solved
Q2 990 solved
Q3 301 solved
Q4 40 solved
My ranking is 1045/ 2964. Starting from ranking 306, players solved only two algorithms. I plan to spend to go over those players with the score 7 as I have.
Here is the link of algorithm 962: Maximum width ramp.
