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

|
}
|

|
fmt.Print(nil, "\n")
|

|
}

func listPushBack(l *piscine.NodeI, data int) *piscine.NodeI {
|
||
|
n := &piscine.NodeI{Data: data}
|
||
5 years ago
|
|
||
|
if l == nil {
|
||
|
return n
|
||
|
}
|
||
|
iterator := l
|
||
|
for iterator.Next != nil {
|
||
|
iterator = iterator.Next
|
||
|
}
|

|
iterator.Next = n

|
var link *piscine.NodeI
|

var link2 *piscine.NodeI

|
|

|
link = listPushBack(link, 3)
|
||
![]()
5 years ago
|
link = listPushBack(link, 5)
|
||
5 years ago
|
link = listPushBack(link, 7)
|
||
5 years ago
|
|
||
5 years ago
|
link2 = listPushBack(link2, -2)
|
||
![]()
5 years ago
|
link2 = listPushBack(link2, 9)
|
||
5 years ago
|
|
||
5 years ago
|
PrintList(piscine.SortedListMerge(link2, link))
|
||
5 years ago
|
}
|
||
|
```
|
||
|
|
||
|
And its output :
|
||
|
|
||
|
```console
