func PrintList(l *piscine.NodeI) {
|
||
5 years ago
|
it := l
|
||
|
for it != nil {
|
||
|
fmt.Print(it.Data, " -> ")
|
||
|
it = it.Next
|
||

|
}
|

func listPushBack(l *piscine.NodeI, data int) *piscine.NodeI {
|
||
|
n := &piscine.NodeI{Data: data}
|
||
5 years ago
|
|
||
5 years ago
|
if l == nil {
|
||
5 years ago
|
return n
|
||
5 years ago
|
}
|
||
|
iterator := l
|
||
5 years ago
|
for iterator.Next != nil {
|
||
|
iterator = iterator.Next
|
||
5 years ago
|
}
|
||
5 years ago
|
iterator.Next = n
|
||
|
return l
|
||
5 years ago
|
}
|
||
|
|
||
|
func main() {
|
||
|
|
||
5 years ago
|
var link *piscine.NodeI
|
||
5 years ago
|
|
||
5 years ago
|
link = listPushBack(link, 1)
|
||
|
link = listPushBack(link, 4)
|
||
|
link = listPushBack(link, 9)
|
||
5 years ago
|
|
||
|
PrintList(link)
|
||
|
|
||
5 years ago
|
link = piscine.SortListInsert(link, -2)
|
||
|
link = piscine.SortListInsert(link, 2)
|
||
5 years ago
|
PrintList(link)
|
||
|
}
|
||
|
```
|
||
|
|
||
|
And its output :
|
||
|
|
||
|
```console
