## **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
|
||
|
|
|
||
|
|
You are given an integer.
|
||
|
|
Your function must return sum of all prime numbers prior to the number exclusively. The number is not included.
|
||
|
|
### Expected function and struct
|
||
|
|
|
||
|
|
```go
|
||
|
|
package piscine
|
||
|
|
|
||
|
|
func Priorprime(x int) int {
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
Here is a possible program to test your function:
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
piscine ".."
|
||
|
|
"fmt"
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
fmt.Println(piscine.Priorprime(14))
|
||
|
|
}
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
Its output:
|
||
|
|
|
||
|
|
```console
|
||
|
|
$> go build
|
||
|
|
$> ./main
|
||
|
|
41
|
||
|
|
```
