Welcome, tech enthusiasts and technology engineers! Today we dive into the world of coding challenges, specifically solution number one: the pyramid challenge. Before we begin, let’s give a round of applause to our grand victor, Vid 32, and our runners-up, A Serious Three and Final Ell. Congratulations to all who participated!
Now, let’s focus on the pyramid puzzle. We will approach this challenge using a bottom-up strategy. The goal is to determine the maximum expected value we can obtain by selecting numbers from the pyramid.

The Bottom Row
Starting from the bottom row, we can easily determine that the maximum value for each number is simply the value of that number itself. Since there are no numbers below them, these values remain unchanged. Let’s take a look at the maximum values for the bottom row:
Moving Up the Pyramid
Now, let’s move to the next row and calculate the maximum value for each number. To find the maximum expected value for a number, we need to consider the value of the number itself along with the greater branch value below it. For example, if we select the number 6, we have a choice between 1 and 2. Since 2 is greater, we add it to 6, resulting in a maximum expected value of 8.
Using this approach, we can calculate the maximum expected values for each number in the second row:
We continue this process, moving up the pyramid and calculating the maximum expected values for each number, until we reach the top row. For each number, we consider the maximum value between the two branches below it.
The Final Result
Once we tabulate all the way to the top, the value in the top row represents the maximum expected value we can achieve. In this case, the solution for the pyramid challenge is 23.
To reconstruct the path, we perform a greedy selection, following the numbers with the highest values. In this case, the path would be: 23 -> 21 -> 18 -> 9. And there you have it!
Why Coding Challenges are Important
Solving coding challenges like the pyramid challenge can be a fun and valuable exercise for technology enthusiasts and engineers. While the puzzle itself may not have direct real-world applications, it helps sharpen our problem-solving skills and introduces us to important programming concepts, such as dynamic programming.
Dynamic programming is a versatile technique that allows us to solve complex problems by breaking them down into smaller, more manageable subproblems. It’s a valuable tool in the programmer’s toolkit, as it enables us to create efficient algorithms and optimize our code.
By participating in coding challenges, we train our brains to think critically and develop simple algorithms. These skills are essential for game programmers, who often need to create custom effects or optimize performance. Additionally, coding challenges help strengthen our code architecture and software engineering skills, which are crucial for creating well-structured, maintainable code.
