Question

Strong Numbers
A strong number is a number such as the square of all its prime divisors is still one of its divisors.

The 3 strong numbers (the last 2 happen to be consecutive) smaller then 10 are: 4, 8 and 9.

For instance the divisors of 8 are 2 and 4 (it is not necessary to count 1 and 8 itself) but only 2 is prime. Therefore, 2^2=4 and 4 is a divisor of 8, so 8 is a strong number.

Tasks:
(easy) Write a program to check if a given number is strong or not.
(medium) Write a program to give all the strong numbers in a given range.
(hard) Write a program to give all the consecutive strong numbers in a given range.

Any programming language is welcome.
Have fun coding!
