## findprevprime
|
||
|
|
||
|
### Instructions
|
||
|
|
||
|
Write a function that returns the first prime number that is equal or inferior to the `int` passed as parameter.
|
||
|
|
||
|
If there are no primes inferior to the `int` passed as parameter the function should return 0.
|
||
|
|
||
|
### Expected function
|
||
|
|
||
|
```go
|
||
|
func FindPrevPrime(nb int) int {
|
||
|
|
||
|
}
|
||
|
```
|
||
|
|
||
|
### Usage
|
||
|
|
||
|
Here is a possible [program](TODO-LINK) to test your function :
|
||
|
|
||
|
```go
|
||
|
package main
|
||
|
|
||
![]()
4 years ago
|
import (
|
||
|
"fmt"
|
||
![]()
4 years ago
|
|
||
|
piscine ".."
|
||
![]()
4 years ago
|
)

|
|
||
|
func main() {
|
||
![]()
4 years ago
|
fmt.Println(piscine.FindPrevPrime(5))
|
||
|
fmt.Println(piscine.FindPrevPrime(4))
|
||
5 years ago
|
}
|
||
|
```
|
||
|
|
||
|
And its output :
|
||
|
|
||
|
```console
|
||
|
student@ubuntu:~/piscine-go/test$ go build
|
||
|
student@ubuntu:~/piscine-go/test$ ./test
|
||
|
5
|

|

|
||
|
student@ubuntu:~/piscine-go/test$
|

```
