Vector Cross Product

Problem

Compute the cross product of two 3D vectors a and b:

c = [a[1]*b[2] - a[2]*b[1], a[2]*b[0] - a[0]*b[2], a[0]*b[1] - a[1]*b[0]]

case 1

in: [[1,0,0],[0,1,0]]

expected: [0,0,1]

case 2

in: [[1,2,3],[4,5,6]]

expected: [-3,6,-3]

case 3

in: [[2,0,0],[0,3,0]]

expected: [0,0,6]
