The population of town A is less than the population of town B. However, the population of town A is growing faster than the population of town B.

Write a program that prompts the user to enter:

1. The population of town A
2. The population of town B
3. The growth rate of town A
4. The growth rate of town B

The program outputs:

1. After how many years the population of town A will be greater than or equal to the population of town B
2. The populations of both the towns at that time.

(A sample input is: Population of town A = 5,000, growth rate of town A = 4%, population of town B = 8,000, and growth rate of town B = 2%.)
