On line number three we take that number and multiply it by the factorial of the number one less than it. K = k + 1 k1 = 1 (Pseudocode is written like code, but meant to be more like human speech.). Here are both approaches as flow charts: The first approach uses a while loop. Then, move on to factorial, length of list, sum of list, simple mathematical formulas in this area.
