### 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
|
|
|
|
|
|
Refactor & Beautify & destruction commit
return early, remove else branches, reorder conditions and top-level functions, remove empty lines, remove unnecessary append(), fix typos, stop using testing package, remove dead code, fix mistakes in subjects, tests and solutions, remove disclaimers, reformat comments, simplify solutions, tests, add more instructions to subjects, remove obsolete files, etc.
Some of the reasons behind those modifications will be added to good-practices.en.md
Some of the exercises are now broken, they will have to be fixed, most of them have a "TODO:" comment.

import "fmt"
|
|
|
|
|
|
|
|
|
|
func main() {
|
|
|
|
|
fmt.Println(FindPrevPrime(5))
|
|
|
|
|
fmt.Println(FindPrevPrime(4))
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|

And its output :
