Intervention Pulse Value

Problem

Compute the effect of a pulse intervention at a given distance: pulse_effect * decay^distance.

Return 0.0 for negative distance, since a pulse cannot affect the past.

Hint

A pulse affects one period; the effect then decays geometrically.

case 1

in: [10,0.5,0]

expected: 10

case 2

in: [10,0.5,3]

expected: 1.25

case 3

in: [5,1,10]

expected: 5

case 4

in: [10,0.5,-1]

expected: 0
