Calculate the factorial of a given number

The given code consists of two functions: FACTORIALVAL and test1. Let’s break down each function and its purpose: FACTORIALVAL(val): This function calculates the factorial value of a given number val. It first checks if the val is equal to 0. If it is, the function immediately returns 1. This is the base case of the factorial calculation, as the factorial of 0 is defined as 1. If val is not equal to 0, the function logs the value of val to the Logger for debugging purposes. It then recursively calls the FACTORIALVAL function with val-1 as the argument and multiplies the result with val. The recursion continues until the base case is reached (when val becomes 0), at which point the recursion stops and the function returns the final factorial value. In summary, the FACTORIALVAL function recursively calculates the factorial of a given number using the formula n! = n * (n-1)!. test1(): This function is not directly related to the factorial calculation. It serves as a test function to showcase the usage of the FACTORIALVAL function. It initializes a variable v with the value 4. It logs the result of calling the FACTORIALVAL function with v as the argument to the Logger. When executed, the test1 function will log the intermediate values of val during the recursive calculation of the factorial of 4 to the Logger, as well as the final factorial value. In summary, the code provides a FACTORIALVAL function that calculates the factorial value of a given number using recursion, and a test1 function that demonstrates the usage of the FACTORIALVAL function by calculating the factorial of 4 and logging the result.
