Computational and Algorithmic Thinking

This 60 min online assessment gives students the opportunity to develop their problem-solving skills through algorithmic thinking. The competition incorporates unique ‘three-stage tasks’ that encourage students to develop informal algorithms and apply them to test data of increasing size or complexity. Topics include: Applying rules, Logic and case analysis and Developing algorithms.

An example questions from the 2023 Intermediate Section (Year 10 and 11)

1957

Katy started with the number 1957. She constructed a new number by:

multiplying the adjacent pairs (1 × 9, 9 × 5, 5 × 7)

writing the answers in order, forming a new number (94535)

She then started with a different number and multiplied the digit pairs in the same way.

The number she constructed was 42488.

How many different starting numbers could she have chosen to get 42488?

1. 1 (B) 2 (C) 3 (D) 4 (E) 5
