-### Instructions
-
-Write the following functions and its struture :
-
-```go
-type Node struct {
-	data int
-	next *node
-}
-
-func SortList(l *node, func cmp(a,b int) bool) *node{
-
-}
-```
-This function must sort the list given as a parameter using the function `cmp` to select the order to apply. It must then return a pointer to the first element of the sorted list.
-
-- Duplications must remain.
-
-- Inputs will always be consistent.
-
-- The type `Node` must be used.
-
-- Functions passed as `cmp` will always return a boolean. If `a` and `b` are in the right order it returns `true`, otherwise it returns `false`.
-
-- For example; the following function used as cmp will sort the list in ascending order :
-
-```go
-func ascending(a, b int) {
-	if a <= b {
-		return true
-	} else {
-		return false
-	}
-}
-```
