Question 15

An algorithm is designed to count how many heart rate readings in a dataset are below 40 beats per minute (bpm).

SET low_count TO 0
FOR EACH reading FROM heart_rates DO
    IF (reading < 40) THEN
        SET low_count TO low_count + 1
    END IF
END FOREACH
SEND 'Low heart rate occurrences: ' & low_count TO DISPLAY

A small dataset is sorted in ascending order and stored in the array heart_rates as follows:

42, 46, 51, 55, 63, 70

Describe one inefficiency when executing this algorithm with this dataset.
