Oh god, arithmetic series... I'm getting flashbacks from discrete math!

i learn a lot standard library from solution

how is this best practises? I don't see anything being done the "best" way.

T_T

While this works, push_back in a loop results in unnecessary allocations as the vector expands, you should reserve the result vector first.

On one side I feel bad for not figure this kind of solutions out just cuz' I forgot certain lang feature exists, on the other side I love checking them out to see how they work.

But hey, practice makes perfect

so this code does not fulfill the technical task of the exercise!!!!
I’m new here, and from the other scripts it’s clear that the technical specifications have been met. Well, sorry, you can’t tell from this.

i dont know it how to work

I have pretty much the same solution and still have the timeout lol
edit: nvm was a one-time thing

One line Code,Nice !

that's cheating! haha, atleast for me it is, i prefer to make more myself, and learn as much as i can!
