L2 Normalize Embedding Vector

Problem

L2 normalization divides a vector by its Euclidean norm, leaving the zero vector unchanged.

Given the vector, return the normalized vector.

Hint

Guard the zero vector case.

case 1

in: [[3,4]]

expected: [0.6,0.8]

case 2

in: [[1,0]]

expected: [1,0]

case 3

in: [[0,0]]

expected: [0,0]
