Question 17

Study the algorithm shown below, which processes telemetry data from a deep-sea research probe.

1  pressureReadings ← [101.32, 104.56, 98.12, 110.45]
2  sensorID ← "PR-09X"
3  index ← 0
4  warningTriggered ← false
5  WHILE index < 4 AND warningTriggered = false
6      IF pressureReadings[index] > 105.0 THEN
7          warningTriggered ← true
8      ELSE
9          index ← index + 1
10     ENDIF
11 ENDWHILE

State the data type of the variable sensorID in the algorithm.
