An ecologist uses the following algorithm to track the number of rare bird sightings on two different islands over several observation windows.
1 islands ← ['Skye', 'Arran']
2 sightings ← [6, 11, 4, 15, 9, 3, 12, 18]
3 count ← 0
4 FOR i ← 0 TO 1
5 island ← islands[i]
6 FOR j ← 0 TO 2
7 observed ← sightings[i * 4 + j]
8 count ← count + observed
9 ENDFOR
10 ENDFOR
Complete the trace table below for this algorithm. You may not need to use all the rows in the table.
| count | i | island | j | observed |
