## Description
|

|
|
<section id="description"> Вектор определяется как имеющий три измерения как представленный упорядоченным набором из трех чисел: (X, Y, Z). <p> Задача: </p><pre> <code>Write a function that takes two vectors (arrays) as input and computes their cross product.</code> </pre><p> Ваша функция должна возвращать значение <code>null</code> на недопустимые входы (т. Е. Векторы разной длины). </p><p></p></section>
