This is the way I went about the "Lowest Common Ancestor" problem. However, keep in mind there are multiple ways to solve this, so don't worry if your solution has variations and it’s entirely possible there are more efficient ways. Feel free to suggest your solution in the comments here or in the original post, but please be respectful of others’ efforts. The Solution The first tendency in this problem is to want to walk back up the tree. This is obviously problematic because we do not have a parent ......
This is the way I went about the "List all anagrams in a word” problems. However, keep in mind there are multiple ways to solve this, so don't worry if your solution has variations and it’s entirely possible there are more efficient ways. Feel free to suggest your solution in the comments here or in the original post, but please be respectful of others’ efforts. The Solution There are many ways to tackle this problem. Ultimately, the main goal of this problem was to be able to return all the anagram ......
I like to keep my brain sharp by working on programming puzzlers. On off weeks I'm going to start posting programming puzzlers I've collected over the years. Hopefully you'll find them as entertaining as I do. The Problem Given a file of all valid words in the English language, write an algorithm that would be suitable for a web page that will list all valid English words that are complete anagrams of the word entered by the user on the page. That is, if the user visits the page and types in POST, ......
This is the way I went about the "The Majority Element” problems. However, keep in mind there are multiple ways to solve this, so don't worry if your solution has variations and it’s entirely possible there are more efficient ways. Feel free to suggest your solution in the comments here or in the original post, but please be respectful of others’ efforts. A Linear-Time, Linear-Space Solution As with so many puzzlers, there is more than one way to tackle this problem. Let’s first consider the more ......
Sorry folks, I totally intended to write a new Little Wonders of C# 6 post this week, but have been ill. I fully intend to continue next week with a new puzzler and a new Little Wonder.
Thanks!

Hey folks, I won’t be posting a new Little Wonders of C# 6 post (you can see my previous posts here) this week. I’ve been preparing a presentation for the St. Louis .NET User Group about all the new C# 6 goodness. If you’ve enjoyed these posts and are in the St. Louis area on April 27th, feel free to pop in and have a listen! I’ll be covering some new wonders I haven’t had a chance to blog about yet. For more information, go to the St. Louis .NET User Group site here. Hope to see you there! Stay ......
This post is another in a series that contains generic utility classes I’ve developed along the way to help make coding a bit easier. If these already exist as part of the framework and I’ve overlooked them, feel free to let me know! And if you know of a better way to implement them, do the same! I’m never too old to learn something new (I hope!). Update: modified the TryDispose() method to check for IsCompleted first and mark any Task exceptions as handled. So recently, I’ve been moving some older ......
Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders post can be found here. This post continues a series of Little Wonders in the BCL String class. Yes, we all work with strings in .NET daily, so perhaps you already know most of these. However, there are a lot of little fun things that the String class can do that often get overlooked. ......

Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders post can be found here. Today we will look at five easy ways to aggregate sequences. Often times when we’re looking at a sequence of objects, we want to do perform some sort of aggregation across those sequences to find a calculated result from the sequence. The methods we will be looking ......
Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders post can be found here. Today we’re going to look at a very small, and sometimes helpful static method of the object class. Of course, we know most of the key methods of the object class by heart, especially the ones we tend to override often such as Equals(), GetHashCode(), and ToString(). ......
I like to keep my brain sharp by working on programming puzzlers. On off weeks I'm going to start posting programming puzzlers I've collected over the years. Hopefully you'll find them as entertaining as I do. Another fun one that I enjoyed solving. As usual with these problems, there’s a fairly straightforward solution -- and a very efficient but harder to find solution. The Problem Given a square 2D array of 1s and 0s, find the starting position (top left row, column) and size of the largest, solid ......

The index of all my past little wonders posts can be found here. Visual Studio 2015 is on the horizon! In fact, some of you may already have played with the preview and seen some of the many neat new things to come – both in the IDE and in the C# language. For those who haven’t been keeping up with the announcements, I’m taking ......
This is the way I went about the “Largest Puddle on a Bar Chart” problem. However, keep in mind there are multiple ways to solve this, so don't worry if your solution has variations and it’s entirely possible there are more efficient ways. Feel free to suggest your solution in the comments here or in the original post, but please be respectful of others efforts. My Approach Of course, the most straight-forward approach could be performed by taking each bar, and finding the pool starting at that bar ......

As some of you already know, today is my last day at Scottrade. It has been a great place to work and I'll miss all the relationships I've formed over the last 5 years immensely! Starting Monday, I will be taking a new position at Amazon.com in Seattle. It should be an exciting new adventure and I look forward to sharing more about my experiences in the days to come! I do intend to continue blogging (after the move settles down) about C# as I'm able, and may mix in some Java as well as I rekindle ......
