Good day! Hopefully your day has started on the right note. Last evening my wife and I watched Ava on Netflix. I like movies with spies and action. Perhaps the plot could have been more realistic and credible. We gave the movie a thumb up.
Earlier today I decided to work on the Facebook coding practice problem Queue Removals. The problem provides a single sample test. In addition, when you run your code, it will be checked against two tests. There are no additional hints. There are no additional tests. Continue reading “Queue Removal in Java”
It is pitch dark in the Twin Cities of Minneapolis and St. Paul. Before calling it a day I decided to try one more practice problem from the Facebook web site. 
It is a Monday morning and it is garbage collection day so I had to put out on the driveway both bins. The company that provides our development with the service collects every week both garbage and recycle bins. All previous companies that I am familiar with collect garbage every week and recycle every other week. To be honest with you, my wife and I would be fine with recycling once a month and if it was not for the potential for smell during summer, garbage every other week.
It is Monday November 09, 2020 and it has been a week since the 
It is a rainy Sunday morning in the Twin Cities of Minneapolis and St. Paul. Rain started last evening around 08:00 PM and according to the weather forecast will subside later tonight around 10:00 PM. Not a nice day to be outdoors or grilling.
My wife cooks lunch during the workdays. We both cook on weekends. We have breakfast which I prepare every day and we both skip dinner. The point that I am trying to make is that we did not start cooking or baking due to the coronavirus pandemic.
The delivery will be sometime tomorrow (Monday).
The news is full of articles and posts about the corona virus. Before getting in panic mode, stop by the CDC “
Over the weekend I watched the YouTube video “
Every work day when quitting time approaches (around 05:00 PM) I check my to-do list. One thing I had for the day was to check is there is a method in a Java class to shuffle the contents of an array. This is a nice mechanism to have in your toolbox. For example, if you want to load a binary tree search (BST) and the data is sorted, the tree will basically load like a linked list. In a BST you can typically find an element in O(log(n)). But if the elements were inserted sorted, the search is performed in O(n) which is slower than O(log(n)). In such cases you can just shuffle the array and then load the BST. 
In this post we will develop a couple methods to collect some information from a binary tree. The first method will be the base, and the second will be an enhancement of the first.
