State the type of validation check to test if the input meets this requirement.

Describe the problem that would be caused in this algorithm if a Value of 1, 0 or less than –1 was input.
See it on the paper → - 0478/21 · May/June 2024 · Q4c[4]
Explain how you should alter the original corrected algorithm to make sure that all the numbers entered are between 1 and 500 inclusive. If any numbers fall outside these limits, a replacement value is requested and entered. You do not need to re-write the algorithm.

Write an algorithm in pseudocode to make sure that an input for the variable Length is between 15 and 35 inclusive. The code must iterate until a valid input has been made and the code must include appropriate messages.

What examiners said
Many candidates correctly stated a range check was the type of check being described.
— Examiner report, May/June 2025, 0478/23 Q4(a)(i) (Cambridge)
Most candidates were able to correctly identify double entry check as the correct answer.
— Examiner report, October/November 2023, 0478/23 Q1 (Cambridge)
Candidates were required to write pseudocode for a range check with given limits that would iterate until a valid input was made. The full range of marks was seen, with most candidates scoring at least one mark.
— Examiner report, May/June 2023, 0478/23 Q5(b) (Cambridge)
