Hey all my friends and readers in the St. Louis area, my team from Amazon is heading to St. Louis to do an in-person hiring event in April!Have you always wanted to work in a place that hires and develops the best? That lets builders be builders? That has excellent benefits and salary/bonuses? That has a clear technical path all the way from entry-level developer to architect and beyond?If you're a developer who loves to solve problems and learn new skills, and be in an environment that encourages ......

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 ......
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 ......
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 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 ......

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 posts can be found here. When I started the “Little Wonders” series, I really wanted to pay homage to parts of the .NET Framework that are often small but can help in big ways. The item I have to discuss today really is a very small item in the .NET BCL, but once again I feel it can help ......
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 posts can be found here. Two posts ago, I discussed the Interlocked Add(), Increment(), and Decrement() methods (here) for adding and subtracting values in a thread-safe, lightweight manner. Then, last post I talked about the Interlocked Read() and Exchange() methods (here) for safely ......
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 posts can be found here. Last time we discussed the Interlocked class and its Add(), Increment(), and Decrement() methods which are all useful for updating a value atomically by adding (or subtracting). However, this begs the question of how do we set and read those values atomically as ......
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 posts can be found here. Often times, we need to update a count in a multi-threaded program. This may be an incrementing, decrementing, or adding a value in a thread-safe manner. This post will discuss one of the lightest ways to do this: the Interlocked class. Problem: Increments Are ......
