I'm going to assume that in this pseudocode, we're accessing the list with 1-based indexing rather than 0-based indexing (i.e. the first element is accessed by list[1] and so on). This code would sum all of the values in the list, so at the end would output 14.
You can check this by following the pseudocode and tracking what the values for `sum` and `spot` are during each of the 6 iterations of the loop. On the first iteration, we have sum = 0 + list[1], spot = 2. In the second iteration, we have sum = (0 + list[1]) + list[2], spot = 3. This continues up through the sixth and final iteration, where sum = 0 + list[1] + list[2] + list[3] + list[4] + list[5] + list[6], sum = 7. Because the loop now completes, we never try to access list[7] (which is good, as the list only has six elements!). If we add up all of these values, we get the answer--14.
