Please give me some advise to solve this question... thanks a lot

I'm having trouble understanding your problem...

I'm particularly not familiar with the functions 'do', 's' and 'od' do...

The variable i starts at 0, then gets incremented by 3 each time through the loop (assuming I'm reading the syntax correctly; I'm not familiar with whatever language that is). The loop ends when i is no longer less than n. That means the loop runs approximately n/3 times.

If you want to get really specific, it actually runs (floor(n/3) + 1) times, where the "floor" function means that you round down to the nearest integer.
