Producer and Consumer – Part 3

It is Friday once again. The cleaning crew is at home. I have been listening to the vacuum for a few hours. They should be done shortly.

I have to get a COVID-19 test this afternoon. On Monday I will be having a procedure and the clinic requires a COVID test in the past 72 hours no matter if you have already received the complete doze of a vaccine. I was going to get this procedure done a couple years ago, but with some travelling plans and then COVID did not have an opportunity to get it done.

Today I suggested to my wife if we could have Asian from Trader Joe’s for lunch. She suggested noodles with an Italian sauce we fixed last week. We were able to fill five one-pint containers and put them in the outside freezer. The sauce turned out very good. We made it last Saturday when my wife’s brother and wife had lunch with us. We used a few pounds of chuck and Italian pureed tomatoes. Hopefully the cleaning crew will leave soon so we can have an early lunch. Continue reading “Producer and Consumer – Part 3”

Remove Duplicates from Sorted Array in Java

Good day. Hope you are doing well. Seems like many companies, businesses and schools are starting to plan on how to conduct business after the COVID-19 pandemic in the USA. It seems like we are getting closer to be able to return to a new normal. I believe that use of masks in public will be required until we achieve herd immunity in different locations. Hope the same is happening in your neck of the woods. Continue reading “Remove Duplicates from Sorted Array in Java”

Letter Combinations of a Phone Number

Today is somewhat colder than yesterday in the Twin Cities of Minneapolis and St. Paul. It seems that we weekend will be quite a bit warmer than the rest of the week. This Sunday is Easter. It should be a nice day if you celebrate the holiday.

Earlier my wife went to get her hair done. Last week she got it cut for the first time since the COVID-19 pandemic started. It is amazing how the past year or so have gone by. Continue reading “Letter Combinations of a Phone Number”

Producer and Consumer – Part 2

Yesterday the temperature in the Twin Cities of Minneapolis and St. Paul reached 72F which is quite pleasant for this time of the year. Today we are expecting 42F for a high. That is a drop of 30F! At least the day is forecasted to be sunny.

I also received a message from Gleves48061@hotmail.com regarding my post Revenue Milestones in Java. Not sure what it was all about so I will not comment on it at this time. If I could get an updated comment, I will review and reply as needed. Thanks. Continue reading “Producer and Consumer – Part 2”

Two Sum – Revisited

It is a very nice sunny day in the Twin Cities of Minneapolis and St. Paul. Today is March 29, 2021 and the high for the day is going to be around 70F. My wife and I talked about grilling chicken for lunch but it is a work day and the process of grilling, eating and cleaning might take a couple hours. That is fine on a holiday.

I decided to attempt to solve all problems in a section of LeetCode. It seems that several problems that I have solved before fall into this collection. I will take a problem from each category a day. Perhaps on weekends I will look at two. Continue reading “Two Sum – Revisited”

Producer and Consumer

Hope you are doing well. I fully understand that not all countries are moving quickly to vaccinate most their population against COVID-19. Hopefully the efforts have already started and will be completed soon. Here in the USA it seems that every state is moving at its own pace. That said, a large amount of people have received at least the first of two jabs. The youngest I know of is of age 21. The world needs to get as much of its population vaccinated as possible to achieve herd immunity. If this is not done the virus will continue to mutate and the threat of COVID-19 might remain for years or decades.

It seems that Israel is leading the vaccination process. As in many other countries, there are some people that do not wish to get vaccinated. The prime minister of Israel has made some clever, and for what I understand legal changes to motivate all their citizens and residents to get a COVID-19 vaccine.

In a nutshell the idea is that the good of the majority needs to prevail. People will not be forced to get a vaccine unless there are medical reasons. Besides that, the population needs to show a vaccine passport to work where there is human contact with others. If the person wishes to attend events and places where they could possibly transmit COVID-19, they need to have a COVID test in the previous 48 hours. The COVID tests used to be free but in the near future people will need to pay for a test. So if a person for without a real medical issue does to get the vaccine but wishes to mix and mingle with others, they will have to pay and get a COVID test every other day. I guess Israel will be one of the countries that will reach heard immunity in the very near future. In my humble opinion, we in the USA need to start thinking about each other and work for a common goal. Continue reading “Producer and Consumer”

Maximum Score of a Good Subarray

Good morning. Hope your day has started on the right note. If you follow this blog you have noticed that I recommend social distancing in order to reduce the chances of COVID-19 to spread in your local community. My wife and I wear a mask when we go shopping. As soon as we return to our vehicle we remove the mask and apply had sanitizer to our hands. We are planning to continue this behavior for the foreseeable future.

My wife has been to the Mall of America a couple times during the pandemic. She and a friend have not been shopping but walking. On each occasion my wife told me that the mall was almost empty with many stores closed. That is a shame. Continue reading “Maximum Score of a Good Subarray”

Merge K Sorted Arrays

Good morning! It is once again Saturday morning during the COVID-19 pandemic. Today is March 13, 2021 and the sun is shining in the Twin Cities of Minneapolis and St. Paul. The forecast calls for the temperature to get up to 58F. For this time of the year it is welcomed. Tomorrow it will be a little cooler and daylight savings time starts at 02:00 AM when the clocks spring forward to 03:00 AM. Tomorrow we lose one hour.

A week or so ago I was talking with an engineer about merging a set of sorted arrays. I also generated the post Merge Sorted Array which probably motivated the exchange. If you take a look at the last post, the idea was to merge two sorted arrays. The obvious next step is to consider multiple sorted arrays of the same or different lengths. In that post we considered two approaches. In the first one we add all the elements from both arrays into a priority queue. We then populate the result array with the elements being removed from the priority queue. Continue reading “Merge K Sorted Arrays”

Merge Sorted Array

Good morning!  Hope your day has started on the right note. The high temperature in the Twin Cities of Minneapolis and St. Paul is forecasted to be about ten degrees less than yesterday. BTW, yesterday the temperature went up to 61F which is the highest this year so far. My wife and I were planning on grilling yesterday but one thing and the other and I ended having BBQ Chicken Teriyaki from Trader Joe’s. Tasty but I prefer my wife cooking (just making points).

It seems that COVID-19 vaccinations are starting to pick up Minnesota. We are behind other states but the expectations are high. We need to hit herd immunity as soon as possible. It seems that masks and social distancing will be a good idea for people with or without the vaccine for the near future until there is enough data to understand if we will need periodic vaccine boosters or not.

Largest Triple Products – Revisited

Good morning! It is 04:15 AM and it is a relatively warm day. Last evening before going to bed I decided to hopefully get up a little earlier than usual. I have a permanent alarm on my phone for 06:00 AM. I use it as a fail-safe in case I do not naturally wake up before. Today I wanted to get this post done and take a look at a test I left running overnight. My wife has a doctor’s appointment early today and it is a 45 minute drive from home. She has to fast so I will follow suit. We should be leaving home around 06:45 AM. Continue reading “Largest Triple Products – Revisited”
