Vector Linear Interpolation

Problem

Linearly interpolate between vectors a and b with parameter t:

lerp(a, b, t) = a + t * (b - a)

Return a list of floats; t = 0 gives a and t = 1 gives b.

Hint

Interpolate each component independently.

case 1

in: [[0,0],[10,20],0.5]

expected: [5,10]

case 2

in: [[1,1],[3,5],0.25]

expected: [1.5,2]

case 3

in: [[2,4],[2,4],0.7]

expected: [2,4]

case 4

in: [[0,0],[4,8],0]

expected: [0,0]
