## itoaprog ##**WARNING! VERY IMPORTANT!** For this exercise a function will be tested **with the exam own main**. However the student **still needs** to submit a structured program: This means that: - The package needs to be named `package main`. - The submitted code needs one declared function main(```func main()```) even if empty. - The function main declared needs to **also pass** the `Restrictions Checker`(illegal functions tester). It is advised for the student to just empty the function main after its own testings are done. - Every other rules are obviously the same than for a `program`. ### Instructions - Write a function that simulates the behaviour of the `Itoa` function in Go. `Itoa` transforms a number represented as an`int` in a number represented as a `string`. - For this exercise the handling of the signs + or - **does have** to be taken into account. ## Expected function ```go func Itoa(n int) string { } ```
