OP solved it, closing

Exactly like my solution.

Probably truth is in the middle.
Knowing how to implement something without built-in functions is important from one hand, but from other hand is crucial for professional programming to know language library for fast-usage of such "ready-made" functions.

I don't think so. It teaches you how not to invent the wheel by utilizing existing functions.

I really like this solution because it doesn't use the math module and it still remains simple.

so get the thing, in this case an array at the ith index, and then since we know it is an array, just get the 0th index

in other words to match our example

1. Get the array at the ith spot
2. and then get the first element of that array

I realize this is a year later but i figured i could still answer.

finally! a piece of code i can understand!

I like this sollution

I thought so too, but notice if the number is < 2, it'll only iterate twice before it reaches that statement.

i like it solution :)

Hu, though there was effectively a problem: the random generator could create negative numbers. I fixed that (this does not happen in the other languages).

you're right i did not htink about it

Well, my dear... Your code is actually wrong. Because of this:

int result =...

EDIT: well, actually no, it's just totally wrong, in fact. It seems it passes the tests only by chance. Now that you can see the other answers, you'll be able to figure it out.
