Normally you can't. You cannot tell if water has been frozen and then thawed.
Answer: Parameters
Explanation:
Whenever a call to a recursive function is made, then the function has its own code and its own set of parameters with local variables. These parameters are within the scope of the recursive function. For example while finding the factorial of a number we are given the function with parameter such as int recursive(int n) where int n is a parameter passed into the function.
