矢量元素的总和

vector = [1, 2, 3, 4, 5]
sum_vector = sum(vector)
print(sum_vector)

import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        int[] vector = {1, 2, 3, 4, 5};
        int sumVector = Arrays.stream(vector).sum();
        System.out.println(sumVector);
    }
}

const vector = [1, 2, 3, 4, 5];
const sumVector = vector.reduce((a, b) => a + b, 0);
console.log(sumVector);
