An algorithm is shown in the pseudocode below:

1      score ← USERINPUT
2      IF NOT(score < 10) AND score < 50 THEN
3          OUTPUT "Standard"
4      ELSEIF score >= 50 AND score < 90 THEN
5          OUTPUT "High"
6      ELSEIF score MOD 10 = 0 THEN
7          OUTPUT "Bonus"
8      ELSE
9          OUTPUT "Invalid"
