High Point in Array

Good morning! It is Friday and the weekend is just around the corner. In the Twin Cities of Minneapolis and St. Paul we received our first snow dusting of the season. Yesterday early morning I drove my wife to a healthcare facility to get a radiological exam. Traffic was heavier than what we expected. We got back home around 09:00 AM. The rest of the day ended for me at 19:00 PM. It was a very long and exciting day.

As the weather changes, I have slightly modified my workdays. I work in 2-hour blocks. The blocks are dictated by the EyeDefender app. I tend to work four to five blocks during the week and one to two on weekends. After each block I get on a stationary bike and pedal backwards for about two minutes and forward for six. This gives me over half an hour of exercise per day and half on weekends.

Starting this week, I will not stop immediately after EyeDefender tells me to do so. Will continue with the bike exercise after each block. Doing this will reduce the blocks to four on workdays. I guess it is better to continue working past the two hours until I reach a normal breaking point based on the task at hand. Will let you know my findings as far as productivity is related early next year.

One last thing, most of the times that I generate a post, I check on the number of subscribers. Today’s count is 10,025 subscribers Thanks a lot!!! This implies that in the very near future I will, in addition to this post, start a YouTube channel with similar content or will just switch to YouTube and discontinue this blog. One way or the other, I will be getting the necessary video hardware and software tools, and will start experimenting with them. I am planning on having the YouTube channel up and running by January 2022. Continue reading “High Point in Array”

Good day. It is Wednesday and it feels like winter is just around the corner in the Twin Cities of Minneapolis and St. Paul.

Earlier today I attended an O’Reilly webinar. The subject was not as interesting as I thought. What called my attention was the fact that I had to download and install the RingCentral app. After the webinar was done I removed the app from my computer. For security reasons, I prefer to keep installed only the apps that I frequently use and download the ones that I seldom use when needed.

The app seems to be easy to use. I checked RingCentral on Wikipedia. The company is traded in NYSE and the company was founded in 1999. In 2019 their revenue was 902.8 million USD. Looks like the founders figured out there was an opportunity to profit during the COVID pandemic, and they offer a good product.

Out of curiosity, I looked up Zoom Video Communications on Wikipedia. I did not know that it was founded in 2011, long before the COVID pandemic. In 2021 their revenue was 2.7 billion USD. Zoom is another app that I install on my computer when needed.

Over the weekend visiting my younger son, the subject of personality types came up. My daughter in law sent me a few links. I have been reading them on and off. Will have more to say about my findings in my next post. Continue reading “Search Insert Position”

First Bad Version

As I mentioned in my last post, over the past weekend my wife and I visited my younger son who lives in Madison, Wisconsin. At some point during a conversation personality types came up. We spent an hour or so on the subject. Towards the end my son’s wife mentioned an article on the subject she found by doing a web search. I asked her to send us the link. She did. I will read the article later today and will comment on my next post.

The technician that was going to fix the issue with our furnace showed up on time. I decided to watch him at work. He opened the furnace and cleared some dead wasps that had come in through the air intake tube. The furnace started to work. He spent some additional time cleaning contacts to increase the current flow.

It seems that our furnace is getting to the point that it will be needing a replacement soon. The technician gave us quotes for three different models. If the furnace continues to operate as intended we would be replacing it towards the end of Spring 2022.

Last night the furnace worked as expected. This morning I increased the temperature setting to the lower level. I li9ke to keep my office at 65F. The rest of the house is set to 68F during winter.

As I am typing this post the “Machine Learning for Algorithm Design” by Maria-Florina Balcan ACM webinar is starting. I will continue with this post as soon as I am done attending the 1-hour event.

OK, I am back. Would like to finish this post before lunch time. Continue reading “First Bad Version”

Split Array Largest Sum

Hope you are doing well on this Friday. This morning my wife and I woke up with outside temperatures in the low 40’s F. I closed the window in the kitchen, set the thermostats to 68 F and started the furnace. This was the first time this season. The furnace ran for a few minutes heating downstairs. The rest of the day we warmed up with the oven and the sun that shined on and off. Beside next Monday and Tuesday that the high temperature will be in the low 70’s F, the high temperatures will be in the low 50’s and 60’s.

My wife woke up not feeling well. It seems that something she ate yesterday did not go well with her. As far as we can tell, both had the same meals. I am feeling well as usual. We were planning on getting a few grocery items this afternoon. We decided to go tomorrow instead.

This morning we spoke with our younger son. It seems that the plans for them visiting us next week have been scrapped. Hopefully we will have an opportunity in the near future to get together.

Spoke with my best friend earlier today. He got back home last Sunday. He was visiting her daughter in Canada. All is well with his family. His wife will be spending a couple more weeks and will return home after her daughter’s birthday. He had to get back earlier this week due to his work schedule.

Find Peek Element

Good day! Hope you are doing well. Today is July 13th, 2021. We are approaching midsummer. Not sure where time is going.

As I mentioned a few posts ago, I attempted some daily problems posted by LeetCode. At this time I am somewhat busy so I have missed a few. Hopefully in a month or two I will have enough time to work on a problem a day; at least the easy and medium. The others may take a couple days. Continue reading “Find Peek Element”

It is another nice day in the Twin Cities of Minneapolis and St. Paul. The temperature will be in the low 70s. I noticed in the Weather Channel app on my phone that a warning of brush fires has been issued in this area. Based on the temperatures above than normal and precipitation below normal, it was going to happen sooner or later. Hope we get some needed rain soon.

On a separate note the relationship between Israel and Palestine has taken a wrong turn. The last administration in the US was moving forward and had achieved peace between the parties. With the current administration thousands of rockets has been launched into Israel. Interesting but about 20% of the rockets launched have killed the terrorists that launched them. Hopefully both sides will be able to get to a new agreement. Continue reading “Search in Rotated Sorted Array”

Find Minimum in Rotated Sorted Array

It seems we are having another nice spring day in the Twin Cities of Minneapolis and St. Paul. The sun is shining and the temperature is forecasted to reach the low 60s. On Saturday we are expecting high in the low 80s. That will be a record day. Will see when it arrives.

My wife and I are planning on grilling on Saturday and Sunday. For one reason and the other we have not enjoyed an “adult beverage” in a couple months. Grilling steaks while having a beer or two on a sunny and warm day is something worthwhile to do on a weekend. Will provide more info on Sunday if I am able to complete a problem and post it.

Path with Minimum Effort – Java

I have been busy with work, reading and experimenting. So far it has been an interesting and rewarding workweek. That said, I am glad that tomorrow is Friday. Due to the COVID-19 pandemic my wife and I do not have big plans for the weekend with the exception of going out for groceries. I assume that you might be in a similar situation.

I decided to tackle LeetCode problem 1631 Path With Minimum Effort. Sometimes I go for the best approach I can came up with. In this case I kind of stopped before implementing it. My first approach timed out as expected. We will discuss the details. My second approach was accepted with a reasonable time. I still want to get one more pass on it but I just do not have time to get that done now. Continue reading “Path with Minimum Effort – Java”
