Vector Normalization

Problem

Return the unit vector in the direction of v: v / ||v||_2.

If v is the zero vector, return a list of zeros with the same length.

Hint

Divide each component by the L2 norm.

case 1

in: [[3,4]]

expected: [0.6,0.8]

case 2

in: [[1,0,0]]

expected: [1,0,0]

case 3

in: [[0,0]]

expected: [0,0]

case 4

in: [[1,1,1]]

expected: [0.5773502691896258,0.5773502691896258,0.5773502691896258]
