Sum Two Arrays In Single Iteration

Summing two arrays in a single iteration can be a handy technique when you want to combine elements from two arrays efficiently. By going through each element of the arrays simultaneously, you can sum them up without the need for extra loops or complicated logic. In this article, we'll walk you through how to sum two arrays in a single iteration using simple code snippets in a programming language like JavaScript.

Let's start by defining two arrays that we want to sum up. For demonstration purposes, let's say we have two arrays: array1 with elements [2, 4, 6] and array2 with elements [1, 3, 5]. Our goal is to sum the corresponding elements from both arrays in a single iteration.

const array1 = [2, 4, 6];
const array2 = [1, 3, 5];

const sumArray = (arr1, arr2) => {
  const sum = [];
  
  for (let i = 0; i < arr1.length; i++) {
    sum.push(arr1[i] + arr2[i]);
  }
  
  return sum;
};

const result = sumArray(array1, array2);
console.log(result); // Output: [3, 7, 11]

In the code snippet above, we defined a function `sumArray` that takes two arrays as parameters. Inside the function, we initialized an empty array `sum` to store the summed up values. We then loop through the arrays using a simple `for` loop, adding the corresponding elements from both arrays and pushing the result to the `sum` array.

When we run the function with our example arrays `array1` and `array2`, we get the desired output `[3, 7, 11]`, which is the sum of each pair of elements from the original arrays.

By using this approach, you can efficiently sum two arrays without the need for nested loops or complex logic. It simplifies the code and makes it easier to understand and maintain. Remember that both arrays should have the same length for this method to work correctly; otherwise, you may encounter index out-of-bounds errors.

Feel free to adapt this code snippet to your specific programming language or requirements. The key takeaway is to iterate through the arrays in parallel, summing up corresponding elements in a single pass for a more efficient solution.

In conclusion, summing two arrays in a single iteration is a useful technique that can come in handy in various programming scenarios. By following the simple approach outlined in this article, you can easily combine elements from two arrays without unnecessary complexity. Happy coding!
