Polyak Averaging Uniform Weights

Problem

Polyak-Ruppert averaging gives each of the k iterates weight 1/k.

Given k > 0, return the list of k uniform weights.

Hint

All weights are equal and sum to one.

case 1

in: [1]

expected: [1]

case 2

in: [3]

expected: [0.3333333333333333,0.3333333333333333,0.3333333333333333]

case 3

in: [5]

expected: [0.2,0.2,0.2,0.2,0.2]
