An environmental telemetry system uses the following algorithm to sort water quality readings:

# sensorData has the format [sensorID, location, turbidityValue]

PROCEDURE bubbleSortSensors()
    SET tempRecord TO []
    FOR i FROM 0 TO LENGTH(sensorData) - 1 DO
        FOR j FROM 0 TO LENGTH(sensorData) - 2 DO
            IF sensorData[j, 2] > sensorData[j + 1, 2] THEN
                SET tempRecord TO sensorData[j]
                SET sensorData[j] TO sensorData[j + 1]
                SET sensorData[j + 1] TO tempRecord
            END IF
        END FOR
    END FOR
END PROCEDURE
