def get_value(captcha:int) -> int:
    '''
    Gets the captcha value for the given integer
    Advent of Code day 1
    A captcha value is determined by the value of n being added to a total if 
    n+1 is the same number as n. This wraps round back to the start, so the end
    value can be equal to the first.

    Parameters:
        captcha: int
            The integer input of what needs to be worked out

    Returns:
        int
            The value that has been worked out according to the day 1 spec
