Write a function scalar_mult(scalar, vector) that takes a number, scalar, and a list, vector and returns the scalar multiple of vector by scalar. code example

Example 1: Write a function that takes in two sorted arrays and returns a new array with all elements sorted not using array method sort.

// const newSortArrays = (arr1, arr2) => {
//     let output = [];
//     while (arr1.length && arr2.length) {
//        if (arr1[0] < arr2[0]) 
//         output.push(arr1[0] < arr2[0] ? arr1.shift() : arr2.shift())
//     }
//     return [...output, ...arr1, ...arr2]
// }

Example 2: Return the Cartesian product of this RDD and another one, that is, the RDD of all pairs of elements (a, b) where a is in self and b is in other.

rdd = sc.parallelize([1, 2])
sorted(rdd.cartesian(rdd).collect())
# [(1, 1), (1, 2), (2, 1), (2, 2)]
