Write a script which produces a table which approximates half-life decay. P(t) = P_0(1/2)^t/t_1/2 Your program should take two inputs: (a) the initial population (P_0) (b) the half-life (t_1/2) in years. Your program should then produce a table (see format below) which gives the decaying population and corresponding time values until the population reaches 1. Your function should allow for repeated operation until a terminating condition (such as negative starting population) is specified. Enter the starting population (billions): 20 Enter the half-life of the material (years): 5
