BST Operations

It is a Saturday morning in the Twin Cities of Minneapolis and St. Paul. It rained last night. Hopefully the day will be dry. I am planning on cooking chicken wings in the gas grill on the deck. There are not too many warm days left to use the grill this season.

A few days ago I started reading chapter four from “Cracking the Coding Interview” by Gayle Laakmann McDowell. For some reason I diverted to adding and deleting values from a BST. I always like to find how others approached the problem. I started watching some videos and reading some articles on the web. Several of the algorithms were convoluted and they seem to fail with different values. So I decided to write some code which seems to work as expected. If you give it a try and find issues please let me know. Continue reading “BST Operations”

Stack Min

It is Monday evening. Yesterday, with the help of my wife we cleaned a spot in my home office and put together the 4K monitor and computer. Later I set up the computer. The monitor is impressive. The only this missing for today is to connect the Azure Kinect DK and start experimenting.

Today I solved (at least I think) the 3.2 question Stack Min from the book “Cracking the Coding Interview”. The question follows:  “How would you design a stack which, in addition to push and pop, has a function min which returns the minimum element. As I am reading the question I want to state that when I was solving the problem, I agreed with the imaginary interviewer that min function would return the min value. We could also have the solution return the minimum element (the actual node), but we decided that that was not the scope of the question. Continue reading “Stack Min”

Three in One

!!! NOTE !!! For some reason I was not able to post the photos I took of the white board.

!!! UPDATE !!! Was able to download and place a different photo of the entire whiteboard.

Once again it is Saturday. My wife and one of her girl friends went out shopping. I still do not understand the attraction of shopping. I guess it works the same way when I wish to stay home working with my computers. Of course if my wife is not out and about I would not be able to be in my home office. Seems like a good arrangement after all.

Yesterday morning the computer I ordered for starting to experiment with Kinect and Azure was delivered home. I have all the pieces so after my wife arrives will be making place in my home office to bring down and connect the components. Hopefully all will go well and I will be able to start experimenting tomorrow morning. I can’t wait. Continue reading “Three in One”

Stack and Queue

I will start this post today and will finish it tomorrow. Today I received the 4K monitor that I ordered last week from Dell. The box looks like it is for a regular flat screen TV. My wife and I moved it downstairs. I will open the box over the weekend. Hopefully the new computer will arrive before the end of the weekend.

Tomorrow came and went. My wife had a dentist appointment, we had to stop by my son’s place and finally we stopped at the grocery store. When we got home it was past 06:00 PM. We go to sleep shortly after 07:00 PM so we sat down in the living room and chatted. Continue reading “Stack and Queue”

Stack Array

It is the Sunday of Labor Week 2019. Woke up as usual, fixed breakfast and then woke up my wife. After having breakfast got ready and went down to my office for my first work block of the day.

Yesterday afternoon we stopped by my son’s place and cooked paella in the wood pit. It was pretty good. This time we did not use red peppers. It seems to taste better with them. Continue reading “Stack Array”
