Question 64

The values in the arrayRainfall array are: 12, 6, 12, 10, 6

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

1  # Weekly Rainfall Tracker
2  SET count TO 0
3  SET T TO 0
4  SET M TO 0
5
6  FOR EACH num FROM arrayRainfall DO
7      SET count TO count + 1
8      SET T TO T + num
9      SEND T TO DISPLAY
10 END FOREACH
11
12 SET M TO T DIV count
13 SEND M 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.
