Question 2

The values in the arrayPackets array are: 25, 9, 25, 14, 8

An algorithm processes these values as shown in the pseudocode below:

1  # Telemetry Packet Tracker
2  SET C TO 0
3  SET S TO 0
4  SET A TO 0
5
6  FOR EACH packet FROM arrayPackets DO
7      SET C TO C + 1
8      SET S TO S + packet
9      SEND S TO DISPLAY
10 END FOREACH
11
12 SET A TO S DIV C
13 SEND A TO DISPLAY

Complete the trace table showing the execution of the algorithm with these five values. You may not need to use all of the rows.
