Python Quiz 1 | Calculates the factorial of a given number using recursion
This is a Python code that defines a recursive function called foo. The function takes an input parameter x and returns the factorial of x.
If the input x equals 1, the function returns 1. Otherwise, it multiplies the value of x with the result of the foo function called with the input parameter x-1. This process continues recursively until x equals 1.
The code then prints the result of calling foo(5), which should output 120 since 5! (5 factorial) equals 120.
In summary, this code calculates the factorial of a given number x using recursion.
