- 4. Word 3 of the term in 3 Down: ________ the _________ (9)
- 5. A ______ used to dry-run pseudocode: one column per variable plus OUTPUT, and a new row each time a statement changes a value. INPUT values come from the question. Word 1 of: _____ _____ (5)
- 6. Every algorithm takes ______ data, carries out processes on it (calculations, decisions, storing in variables or arrays), then gives OUTPUT results. Word 1 of: _____, _______, output (5)
- 8. Python for FOR i ← 1 TO n. ______() stops before its end value, so use n + 1 to include n. A third argument is the STEP; a negative step counts down. Word 4 of: for i in _____(1, n + 1): (5)
- 9. Word 2 of the term in 6 Across: _____, _______, output (7)

- 1. State how many times the loop repeats or the condition it stops on, and what happens to the data each time round, e.g. each mark is added to Total. Word 1 of: __________ a loop (10)
- 2. Work through the loop body once per pass, recording changed values in a new row each time. Test the condition before the body for WHILE and after it for REPEAT. Check the final row. Word 1 of: _______ a loop (7)
- 3. State, in order and in plain words, what each part of the algorithm does with the data: set up variables, what the loop repeats, what the decision does, then the output. Word 1 of: ________ the _________ (8)
- 7. Word 2 of the term in 5 Across: _____ _____ (5)
- 8. Running an algorithm by hand with test values, then comparing the inputs with the final outputs to work out its purpose, such as totalling, counting or finding the largest. Word 2 of: dry ___ (3)
