How to Sum Array of Numbers in Ruby? 💎

Are you struggling to find an easy way to sum an array of numbers in Ruby? Look no further! In this guide, we'll explore a simple and efficient solution to tackle this common problem. Let's dive right in! 💪

The Problem 🤔

So, you have an array of integers, and you want to calculate their sum. For instance, consider the following array:

array = [123, 321, 12389]

How can we get the sum of all the numbers in this array? 💡

The Solution 🌟

The good news is, Ruby provides multiple ways to sum an array of numbers. Let's explore two of the most popular and convenient methods.

Method 1: Using the inject Method 🚀

Ruby's inject method is an excellent option to calculate the sum in a concise and elegant way. Here's how you can use it:

array = [123, 321, 12389]
sum = array.inject(0) { |result, element| result + element }

In this example, we start with an initial value of 0 (specified as the argument to inject). Then, for every element in the array, we add it to the result. The final result is stored in the sum variable.

Method 2: Using the sum Method 🎯

Ruby 2.4 introduced the sum method as a convenient way to calculate the sum of an array of numbers. Here's how you can use it:

array = [123, 321, 12389]
sum = array.sum

Yes, it's as simple as that! Just call the sum method on your array, and it will return the sum of all the numbers.

Choosing the Right Method 😎

Both methods are valid, but which one should you choose? It depends on your specific needs and the version of Ruby you are using.

• If you're running Ruby 2.4 or newer, the sum method provides a clean and straightforward solution. It's easy to read and requires less code.

• If you're using an older version of Ruby or want more control over the summing process, the inject method gives you the flexibility to customize the logic.

Don't worry; both methods are efficient and will get the job done! 👍

Time to Sum it Up! ✨

Now, armed with the knowledge of these two powerful methods, you can easily sum an array of numbers in Ruby. Whether you prefer the elegance of the inject method or the simplicity of the sum method, you have the tools to conquer this problem.

So go ahead, give these methods a try, and start summing those arrays like a Ruby pro! Happy coding! 😄
