SST Yr8 - NCCE - Algorithmic Thinking

Question 1: Identify the correct definition of decomposition.

• A Creating a flowchart to outline how the system will work.
• B Identify the appropriate variable names to use in the program.
• C Hiding unnecessary data/detail and focusing on the key data/detail.
• D Splitting a program into smaller subprograms.

Question 2: Identify the searching algorithm.

• A Merge
• B Bubble
• C Linear
• D Insertion

Question 3: Identify the output from this pseudocode program when the number 3 is input first and then the number 2 is input: input first input second print(first ^ second)

• A: 5
• B: 6
• C: 8
• D: 9

Question 4: The following algorithm should output the numbers 10 11 and 12. Identify the logic error in the algorithm. counter = 10 do print(counter) counter = counter + 1 until counter = 13

• A count = 10 should be counter = 9
• B do should be while
• C print(counter) should be print(counter-1)
• D until counter = 13 should be counter = 12
