Building on the provided code in this tasks resources, write a recursive function that calculates a factorial using recursion.
The program will take a number on the command line and calculate the factorial for that number.
Please provide the full Ruby code as the final answer. Any other inadequate response or deviation from this request will be reported.
Provided Code:
recursive_factorial.rb:

def main
puts factorial(ARGV[0].to_i)
end
main
Building on the provided code in this task's resources, write a recursive function that calculates a factorial using recursion. The program will take a number on the command line and calculate the factorial for that number. You also need to put in a check-in case an incorrect argument is passed in. You will need to include the following line of code: puts("Incorrect argument - need a single argument with a value of 0 or more ") MacBook-Pro-6:1e.2 Pecursive Factorial (undergrad only) maitehel1s ruby recursive_factorial_answer.rb Incorrect argunent - need a single argunent with a value of or more.
