Write a method that has an input parameter 'digits' that represents a BINARY number, but is ACTUALLY a long integer in base 10. Write a RECURSIVE method to compute the decimal equivalent of this binary representation. Your solution MUST be recursive with no loops of any kind. I suggest writing the recursive method as a helper-method so you don't have to use the super long name for the method. For example, the body of my method is: return biToDeci(digits); which calls the helper-method 'biToDeci' which is where I put the entire recursive solution. As a precondition you may assume the input parameter will ONLY contain the digits '0' and '1' and will be a non-negative number that fits in the 'long' data-type. FYI: MY recursive solution to this problem is a one-liner!
