## **WARNING! VERY IMPORTANT!**
|
||
|
|
|
||
|
|
For this exercise a function will be tested **with the exam own main**. However the student **still needs** to submit a structured program:
|
||
|
|
|
||
|
|
This means that:
|
||
|
|
|
||
|
|
- The package needs to be named `package main`.
|
||
|
|
- The submitted code needs one declared function main(```func main()```) even if empty.
|
||
|
|
- The function main declared needs to **also pass** the `Restrictions Checker`(illegal functions tester). It is advised for the student to just empty the function main after its own testings are done.
|
||
|
|
- Every other rules are obviously the same than for a `program`.
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Write a function `ListSize` that returns the number of elements in a linked list `l`.
|
||
|
|
|
||
|
|
### Expected function and structure
|
||
|
|
|
||
|
|
```go
|
||
|
|
type NodeL struct {
|
||
|
|
Data interface{}
|
||
|
|
Next *NodeL
|
||
|
|
}
|
||
|
|
|
||
|
|
type List struct {
|
||
|
|
Head *NodeL
|
||
|
|
Tail *NodeL
|
||
|
|
}
|
||
|
|
|
||
|
|
func ListSize(l *List) int {
|
||
|
|
|
||
|
|
}
|
||
|
|
```
