Default Arguments HackerRank Solution

This Python program is about using default arguments in function definitions. It defines a function 'print_from_stream' that takes two arguments: a number 'n' and a 'stream'. If no stream is provided, it uses an 'EvenStream' by default. The function initializes the stream and then prints the next 'n' numbers from it.

Here is the Default Arguments HackerRank Solution HackerRank solution using CodeRankGPT:

The solution works by defining a function that takes a stream object as an argument. This stream object must have a 'get_next' method that returns the next number in the sequence. The function first calls the '__init__' method on the stream object to ensure it is properly initialized. Then, it enters a loop that runs 'n' times. In each iteration of the loop, it calls the 'get_next' method on the stream object and prints the returned number. If no stream object is provided when the function is called, it uses a default 'EvenStream' object.


def print_from_stream(n, stream=EvenStream()):
    stream.__init__()
    for _ in range(n):
        print(stream.get_next())
