This assignment took me the longest to solve from all the assignments in the 3 courses and I got a bit frustrated along the way. The reason it took me so long was, that both, the LLM and I, didn’t fully understand how the magic summation really works. The example given in the description doesn’t capture the hole picture and the python 2.7 code with the iterator is not easy to understand (thus the word magic summation).
Here I give you an easy example that captures the entirety of this magic summation:
Calling the function with n=5 and a random seed of 555 returns the magic sum 8.
magic_summation_python27.py 5 555 → magic sum: 8
Why is that? Let me break this down into four steps:
- A magic list of 5 integer number is created: [1, 2, 3, 4, 5]
- With the random seed of 555 a list of unique indices that will be removed is created: [1, 5, 4, 3]
- Now one after another, the magic list is shortened:
a) Remove 1st element → [1, 3, 4, 5]
b) Remove 5th element → no 5th element
c) Remove 4th element → no 4th element
d) Remove 3rd element → [1, 3, 4] - Divide two consecutive elements in the magic list and sum the results:
a) 3/1 = 3
b) 4/3 = 1
c) Last element: 4
Magic sum: 3 + 1 + 4 = 8
Hint: Maybe it is helpful to provide the LLM with this detailed example. Let me know, whether it worked or not. Good luck with the assignment and hang in there!!!
