### Instructions
|
||
|
|
|
||
|
|
Write a function called `SaveAndMiss()` that takes a `string` and an `int` as an argument. The function should move through the `string` in sets determined by the `int`, saving the first set, omitting the second, saving the third, and so on, in a 'save' and 'miss' fashion until the end of the `string` is reached. Return a `string` containing the saved characters.
|
||
|
|
|
||
|
|
> If the `int` is `0` or a negative number return the original `string`.
|
||
|
|
|
||
|
|
### Expected function
|
||
|
|
|
||
|
|
```go
|
||
|
|
func SaveAndMiss(arg string, num int) string {
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a possible program to test your function:
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
"piscine"
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
fmt.Println(piscine.SaveAndMiss("123456789", 3))
|
||
|
|
fmt.Println(piscine.SaveAndMiss("abcdefghijklmnopqrstuvwyz", 3))
|
||
|
|
fmt.Println(piscine.SaveAndMiss("", 3))
|
||
|
|
fmt.Println(piscine.SaveAndMiss("hello you all ! ", 0))
|
||
|
|
fmt.Println(piscine.SaveAndMiss("what is your name?", 0))
|
||
|
|
fmt.Println(piscine.SaveAndMiss("go Exercise Save and Miss", -5))
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output:
|
||
|
|
|
||
|
|
```console
|
||
|
|
$ go run . | cat -e
|
||
|
|
123789$
|
||
|
|
abcghimnostuz$
|
||
|
|
$
|
||
|
|
hello you all ! $
|
||
|
|
what is your name?$
|
||
|
|
go Exercise Save and Miss$
|
||
|
|
```
