Normalized Descent Direction

Problem

The steepest descent direction is -grad / ||grad||.

Given a nonzero gradient vector, return the unit descent direction.

Hint

Negate and divide by the Euclidean 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,-2]]

expected: [0,1]
