Introduction
It is a weekly contest again called weekly contest 112. I played the contest and this time I tried different strategies in the contest and after the contest. I spend first 5 to 10 minutes to read all four algorithms from last one to the first one, and after the contest, I try to finish all the algorithms if there are unsolved algorithms.
My performance
Here is the my performance. I solved two algorithms. I only had 10 minutes for the third and fourth algorithms, however, I already spent first 5 to 10 minutes to go over the problem statements first.
I had problems to understand the algorithm Q3, the bag of tokens. Actually a bag of token may not be ordered. I thought that the tokens are ordered like an array. After the contest, I spent extra 30 minutes to finish the algorithm "the bag of tokens".
I learned the algorithm 4 from discuss, I will write one solution later.
I need to share my discuss and go over some sharings first.
Follow up
April 2, 2019I have time to learn how to solve union find tagged algorithm, Leetcode 947 Most stones removed with same row or column, which is the third algorithm in the contest.
I like to go over a few solutions and then learn to solve them one by one using C#. I failed to solve an algorithm in March 2019 in code screen, which is the same level of Leetcode 947.
Actionable Items
April 2, 2019
I need to push myself to work on all the algorithms in each weekly contest. It is not too difficult to learn various ideas to solve the problem, I can just go over top ranking 20 players and then study a few solutions.
