How To Sum Elements At The Same Index In Array Of Arrays Into A Single Array

Arrays are a fundamental concept in programming, serving as a handy way to store collections of data. Array of arrays, also known as a multidimensional array, takes things up a notch by allowing you to create an array where each element is, in fact, another array. If you've ever found yourself needing to sum elements at the same index in an array of arrays into a single array, this guide is here to help you sail through that process like a pro.

First things first, let's clarify what we mean by summing elements at the same index. Suppose you have an array of arrays like this:

[[1, 2, 3], [4, 5, 6], [7, 8, 9]]

Your goal is to sum the elements at the same index position from each sub-array and create a new array that contains the results. For the above example, the desired output should be:

[12, 15, 18]

To achieve this, you can utilize a straightforward approach using a loop. Here's a step-by-step guide to help you accomplish this task efficiently:

Step 1: Initialize an empty array to store the final result.

result = []

Step 2: Determine the length of the sub-arrays to ensure consistent indexing.

length = len(arrays[0])

Step 3: Iterate through each index position up to the determined length.

for i in range(length):

Step 4: Use a list comprehension to sum elements at the same index from each sub-array.

result.append(sum(arrays[j][i] for j in range(len(arrays))))

Step 5: Voila! You've successfully computed the sum of elements at the same index from the array of arrays into a single array.

print(result)

By following these steps, you can streamline the process of summing elements at the same index in an array of arrays effortlessly. Don't hesitate to experiment with different array structures and sizes to deepen your understanding of this concept.

In conclusion, mastering the art of working with arrays of arrays opens up a realm of possibilities in your coding journey. Whether you're a seasoned developer or just starting, honing your skills in manipulating multidimensional arrays will undoubtedly enhance your problem-solving capabilities. Embrace the challenge, stay curious, and never underestimate the power of practice in refining your coding prowess. Happy coding!
