Affine Combination Check

Problem

Return True if the given weights form an affine combination, meaning they sum to 1 within a tolerance of 1e-9. Otherwise return False.

Hint

Only the sum of the weights matters for an affine combination.

case 1

in: [[0.5,0.5]]

expected: true

case 2

in: [[0.2,0.3,0.5]]

expected: true

case 3

in: [[1,1]]
