Hint: This pseudocode calculates the sum of even numbers up to a given even number N.
// The pseudocode calculates the sum of even numbers up to N.
total_sum = 0

INPUT N // A positive even integer from the user, assume numeric
WHILE counter_variable <= N:
total_sum = total_sum + counter_variable
counter_variable = counter_variable + 2
END WHILE
PRINT total_sum
