Question

match the term that best fits the examples
using the remainder to
determine whether a
number is even or odd.

1. take the input value

and compare to the
stored value

1. if the input value is

greater than the
stored value, add 1

1. if the input value is

less than the stored
value, replace the
input value with the
stored value

1. if the input value is

the same as the
stored value, print an
error message

1. decomposition
2. pattern recognition
3. algorithm
4. abstraction

Explanation:

• The first example uses checking a remainder pattern (even/odd is a pattern based on division by 2 remainder) to classify numbers, which fits pattern recognition.
• The second example is a step-by-step, ordered set of instructions to complete a task, which is the definition of an algorithm.

Answer:

• "Using the remainder to determine whether a number is even or odd." → 2. Pattern recognition
• The numbered step-by-step instructions → 3. Algorithm
