While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

well, you can see that when you they call the method, they pass it a 9 as the n argument

and then it is used in the for loop

that will iterate from 3 up to 9

that is 6 times, so it will do whatever is inside of the brackets by 6 times

Since it is p <= 9 should it be 7 times?

[shadow karma]

i get 64

[floral raft]

3,4,5,6,7,8,9

[keen lake]

you're right

Ok - what is k1 to k3 after the first loop?

[shadow karma]

2

2

2

[floral raft]

Incorrect

[shadow karma]

how

[keen lake]

well the first time it iterates, you have k1 = 1, k2 = 1, and k3 = 2
the next time, it goes k1 = 1 because k2 was 1 on the previous iteration, k2 = 2 because k3 was 2, and k3 = 1 + 2, so it is 3, and then again and again

you have 2 iterations there

You have to think in steps and what is true NOW versus in the past or future. Slow and steady.

[keen lake]

yeah, think about it like there is no for loop, and it's just the same chunk of code repeated 7 times

you can see how the variables are constantly rewriting their past versions

(It also works out to be a very famous sequence)
