### Instructions ### Instructions
Écrire une fonction `CountIf` qui retournes le nombre d'éléments d'un tableau de `string` pour lesquels la fonction `f` retourne `true`. Write a function `SortedListMerge` that mereges two lists, `n1` and `n2`, but it as to join them in ascending order.
### Fonction attendue - Tip each list as to be already sorted.
- Use pointers when ever you can.
### Expected function and structure
```go ```go
func CountIf(f func(string) bool, tab []string) int { func SortedListMerge(n1 *Nodee, n2 *Nodee) *Nodee {
} }
``` ```
### Utilisation ### Usage
Voici un éventuel [programme](TODO-LINK) pour tester votre fonction : Here is a possible [program](TODO-LINK) to test your function :
```go ```go
package main package main
import ( import (
"fmt" "fmt"
piscine ".." piscine ".."
) )
type node = piscine.Nodee
type nodes = piscine.Nodee
func PrintList(l *piscine.Nodee) {
m := l
for m != nil {
fmt.Print(m.Data, " -> ")
m = m.Next
}
fmt.Print(nil)
fmt.Println()
}
func listPushBack(l *piscine.Nodee, data int) *piscine.Nodee {
n := &piscine.Nodee{Data: data}
if l == nil {
return n
}
iterator := l
for iterator.Next != nil {
iterator = iterator.Next
}
iterator.Next = n
return l
}
func main() { func main() {
tab1 := []string{"Hello", "how", "are", "you"} var link *node
tab2 := []string{"This","1", "is", "4", "you"} var link2 *nodes
answer1 := piscine.CountIf(piscine.IsNumeric, tab1)
answer2 := piscine.CountIf(piscine.IsNumeric, tab2) link = listPushBack(link, 5)
fmt.Println(answer1) link = listPushBack(link, 3)
fmt.Println(answer2) link = listPushBack(link, 7)
link2 = listPushBack(link2, -2)
link2 = listPushBack(link2, 4)
PrintList(piscine.SortedListMerge(link2, link))
} }
``` ```
