An algorithm is needed to process a sequence of numbers. Numbers may be positive or negative and may be integer or decimal. The algorithm will: • prompt and input one number at a time until the value zero is input • sum the negative numbers • sum the positive numbers • when zero is input, output the two sum values and then end. Describe the algorithm needed. Do not include pseudocode statements in your answer. [5]
