used to reset the value of a points score of each round of an interactive quiz. There are 5 rounds. Can you identify the logic error? UNTIL LOOP Write an algorithm that calculates the total value of the points gained in each round of the quiz using the array round. This can be written in pseudocode UNTIL LOOP
