Leetcode 910. Smallest Range II

Sept. 29, 2018

Introduction


It is such a big surprise that I found an excellent player who also wrote blogs related to weekly contest 103. The algorithm 901 is so tough for me to come out the solution to pass all test cases in the contest.

Here is the blog written in Chinese.

Leetcode discuss


Here is the post to read.



Leetcode 911 online election

Sept.29, 2018

Introduction


It is such a great blog related to the medium level algorithm 911, online election. Here is the blog.

A very good algorithm blog

Sept. 29, 2018

Introduction


It is time for me to study leader board after weekly contest 104. Now it is 11:02 PM, I came cross this blog and I am so surprised that the blogger is such a great worker. The algorithm online election will be my most favorite algorithm in short future.

Here is the blog.

Very good writing


The player can rank up to top 400, here is one blog to document his experience. I also learn something from his blog related to hackearth contest.

915. Partition Array into Disjoint Intervals

Sept. 29, 2018

Introduction


It is the medium level algorithm in the weekly contest 104. I wrote the solution using two iterations of the array, one is to keep maximum of prefix and minimum of suffix.

My practice


Here is my discuss link. I also learned to write one pass, and then I wrote the reply in one of posts here.

916. Word Subsets

Sept. 29, 2018

Introduction


It is a medium level algorithm, and I solved it by the first submission using counting sort.

My practice in the contest


Here is my discuss link. I also wrote some reply in other's discuss. Here is the link.



Leetcode algorithm categories

Sept. 29, 2018

Introduction


It is important to get organized and well-prepared for any trial, no matter it is onsite, phone screen, or project at work, weekly Leetcode contest, or any other activities. In order to get better on algorithm and data structure, I start to play Leetcode weekly contest, and also I take some time to study leader board after the contest. Today I finished Leetcode weekly contest 104, and then I spent time to look up the leader board, now it is 9:49 PM.

One blog


I came cross this Leetcode category, and then I added to my Leetcode github page. It is important for me to look up and get the idea how to get more organized.

One of my favorite is monotonic data structure. Here is the link called Monotonic queue.

It is also very important for me to understand how hard the young people are working.

I like to gather data how many algorithms players finish. Several profiles are very interesting to look up.

One is with a lot of ICPC contest experience.




weekly contest 104

Sept. 29, 2018


Introduction


It is the weekly leetcode contest. I solved second and third algorithms, but the first algorithm is related to great common divisor, but somehow I did not get the idea. I tried over 20 minutes to think about a solution after one failed test case on the algorithm one.

There is a graph problem which is hard level, I did not have time to figure out the solution.

Progress report


My ranking is 1076/2579, score 11, finish time: 59:09. I could not score anything after the first hour.

Having good time

Sept. 27, 2018

Introduction


It is surprising to learn that I had good time to work on one algorithm. What I did is to work on the algorithm, first 30 minutes to think about all the ideas. And then I spent another 30 minutes to go over various ideas on leetcode discuss. And then I spent time to write some code based on ideas I chose from those sharings.

I worked on the algorithm called longest word in dictionary, I had such good time to learn how to write Trie data structure, and also learned one solution using quick and easy to write using HashSet.

I also studied grand yang blog and read some tips written in Chinese.

Have good time


Sometimes the programmer can be so easily satisfied and be happy. Sometime it helps me a lot to warm up my brain using an easy level algorithm.

Here is the folder I created on my github for the algorithm.

There are so many good ideas I like to try. I like the idea to sort by word's length. Maybe I should exhaust all possible ideas, and list 10 ideas here.


Ideas about training


I always like to find good ideas to train myself in daily basis. I trained the easy level algorithm using hashset, trie, queue, and then use recursive function.

One of ideas is to train myself every week based on how many times I write on recursive function, hashset, or trie, or tree.

One way to get better is definitely to write code all the time. 

I wish that I can do more to make Leetcode discuss community better, it is very comfortable for me to stay in and continue to practice.

720. Longest Word in Dictionary using Trie (II)

Sept. 27, 2018

Introduction


It is my best time to enjoy coding and learn Trie implementation. I wrote one using more than 30 minutes, at the end of practice, I still am not sure the idea. The recursive idea is hard for me to figure out somehow.

My practice


Here is my discuss link.

720. Longest Word in Dictionary using Trie

Sept. 27, 2018

Introduction


It is an easy level algorithm tagged by HashTable. I had good time to learn to write a solution using Trie.

Solution using Trie


I understand that there must be an quick and easy to write solution for the easy algorithm. To write a Trie is not so easy, and I have to think carefully and then need 10 to 20 minutes to come out code.

Here is my discuss link using Trie. I also wrote some comment in one popular discuss, here is the link.

Customer obsession, one extra reputation

Sept. 26, 2018

Introduction


It is called customer obsession principle. I like to serve leetcode discuss community, and then I started this September to share as many as possible my practice of Leetcode easy level algorithm. today I found out that my reputation is 10, one addition vote from 9. I had reputation more than one week.

It is tough for me to serve Leetcode discuss. I try to find which post I wrote helps me to gain one reputation. It is so hard for me to find out.

I did not have all the discuss link I shared before. I have more than 50 posts, I can certainly go one by one to look up.

I found the vote 


Here is the post I got one up vote and my reputation now is 10.


Longest univalue path algorithm

Sept. 26, 2018

Introduction


It is 10:00 PM and it is time for me to be an interviewer on interviewing.io. I chose to use longest univalue path algorithm again.

I gave a few hints to the interviewee today, and then I also tried to catch up some reading from discuss of the algorithm.


Suite season 7

Sept. 26, 2018

Introduction


It is 10:06 PM. I like to write a blog related to a small topic, how often I should spend time to watch Suites. It is such a great show for me to have some good entertainment.

As a software programmer, I find out that we do not have chance to practice talk like actor/ actress in the show. I really like to meet other talent software programmers, one way I can do that is to work on easy level algorithms, and then go over some ideas. I can find so many talent programmers in Leetcode contest global ranking, and also in discuss as well.

I like to find 30 minutes show times at least one or twice in a week. It may help me to develop some good habit to learn to speak very well, and also expand my vocabulary.


720. Longest Word in Dictionary (I)

Sept. 26, 2018

Introduction


It is an easy level algorithm. But I did think about Trie for a few times in my first 20 minutes brainstorm to find all ideas. Here are things I thought about.

1. Sort the words by length
2. Check word by word by length, starting from length = 1, maximum length is 30
3. Use Trie data structure

It is definitely a good algorithm to work on. I like to get some experience from all the sharing first.

My practice


Here is my practice using hashset only. It is easy and quick solution.

9/26/2018
Here is my practice using Queue.
Here is my practice using recursive function.

138. Copy List with Random Pointer

Sept. 25, 2018

Introduction


It is a medium level tree algorithm. I practiced once and also used this algorithm to interview a few times on interviewing.io as an interviewer.

I like to write a C# solution for this medium level algorithm. And also I like to share my experience to encourage players to work hard on basics. I had chance to work on the algorithm in the meeting, I solved the algorithm in less than 28 minutes. Since I solved the clone graph and also worked on copy a binary tree with a random pointer, I was able to solve the algorithm quickly. Another reason is that I use a few simple test cases to help me reason and develop the code.

My practice


I will write the code and also share my analysis as well.

Spotify

Sept. 22, 2018

Introduction


It is time for me to study one business a time. I think that it is best for me to learn more business. Stream service is so popular and I just had experience to learn Amazon prime video this past June 2018.

I just read one article written by a software engineer in Spotify.


Everyone can be ambitious but action speaks its own

Sept. 22, 2018

Introduction


It is most common talk in the mock interview on interviewing.io. I usually ask the interviewee what companies to prepare for the interviews. A lot of times the players tell me that eventually they like to work for big 4 software companies. I also like to say that over years as well.

Action speaks its own


It is hard to act on it. I learn how to manage the practice, use metrics to read data and then analyze my progress, submission in the last 12 months, contest global ranking, solved algorithms.

I started to work on Leetcode algorithm from January 2015. But I did not learn how to solve more algorithms in short time. After one year, second year, third year, now it is fourth year. I got a coach in June for two weeks, and then he gave me advice in July 10, 2018.

One thing I like to do is to work on Leetcode easy level algorithm, solve 200 easy level algorithms first. I started this July 10, 2018, right now I have solved 120 easy level algorithm. Still I have 80 algorithms to go.

The secret - talk to the best player


I learn to talk to the best player, and be humble, take advice.



Leetcode contest study

Sept. 22, 2018

Introduction

It is the study called Leetcode weekly global contest ranking.  I studied top 300 global ranking of Leetcode contest, and then I found some article to read.

Leetcode progress study


Here is my Leetcode progress: 37762, contest ranking 14347.


I know that next 200 algorithm to work on, 50 will be easy level algorithms, rest will be medium level or higher.

Compared to the author of article, I learn that I have to work on another 200 algorithms at least, and also I need to push myself work hard on Leetcode algorithm. I need to advance my global contest ranking to top 5000 first.

Leetcode progress report

Sept. 22, 2018

Introduction


It is the learning process for me how to handle frustration and failure. I learn to read my own data first. Here is my Leetcode progress report. I finished 219 algorithms, and played four contests. My ranking is 14347/ 69980.

I know that I have to be patient and then work on more Leetcode algorithms.

A comparison


I had chance to meet a new graduate from university in China, and he finished over 400 algorithms, and his contest ranking is around 2000.

He started to practice Leetcode from 2017 Oct., before that he worked on BOJ and worked on more than one hundred algorithms.

My Leetcode ranking is 37762. Contest ranking is 14347. I checked in Sept. 22, 2018, 11:11 AM.


I like to find ways to complete another 200 Leetcode algorithms in next 6 months.

I like to work on two targets, the first one is to complete another 200 Leetcode algorithm practice. The second one is to advance ranking of contest to first 2000 as well. The young graduate is my role model.


My fourth interview on interviewing.io

Sept. 22, 2018

Introduction


It was my 9:00 PM mock interview, and it was my fourth interview as an interviewee. I had chance to work with the interviewer, and I answered the first three algorithms and explained the ideas in the first 12 minutes, and then moved on the fourth algorithm which is the hard level Leetcode 212 Trie. I explained the idea how to solve the algorithm, and wrote the code until we reached 45 minutes mark. We chat about 15 minutes about practicing and learning.

I had 10:00 PM mock interview as an interviewer, and I did not explain to the interviewer of 9:00 PM until 10:01 PM. I rushed to say goodbye and then started my 10:02 mock interview.
