Finding the average of all elements in a vector

Calculating the average of all elements in a vector is a common operation in many programming scenarios. In this blog post, we will explore how to accomplish this task using different programming languages.

Python

vector = [1, 2, 3, 4, 5]
average = sum(vector) / len(vector)
print("The average is:", average)

In Python, we can use the sum() function to get the sum of the elements in the vector, and then divide it by the length of the vector using the len() function. The result is the average of all elements.

JavaScript

const vector = [1, 2, 3, 4, 5];
const sum = vector.reduce((acc, curr) => acc + curr, 0);
const average = sum / vector.length;
console.log("The average is:", average);

In JavaScript, we can use the reduce() method to iterate over all elements in the vector and calculate their sum. Then, we divide the sum by the length of the vector to get the average.

Java

import java.util.Arrays;

public class AverageCalculator {
    public static void main(String[] args) {
        int[] vector = {1, 2, 3, 4, 5};
        int sum = Arrays.stream(vector).sum();
        double average = (double) sum / vector.length;
        System.out.println("The average is: " + average);
    }
}

In Java, we use the Arrays.stream() method to convert the vector into a stream of integers. Then, we use the sum() method to calculate the sum of all elements. Finally, we divide the sum by the length of the vector and cast it to a double to obtain the average.
