sortlist

Instructions

Write a function that must:

• Sort the list given as a parameter, using the function cmp to select the order to apply,

• Return a pointer to the first element of the sorted list.

Duplications must remain.

Inputs will always be consistent.

The type NodeList must be used.

Functions passed as cmp will always return true if a and b are in the right order, otherwise it will return false.

Expected function

type Nodelist struct {
	Data int
	Next *Nodelist
}

func SortList (l *NodeList, cmp func(a,b int) bool) *NodeList{

}

• For example, the following function used as cmp will sort the list in ascending order :

func ascending(a, b int) bool{
	if a <= b {
		return true
	} else {
		return false
	}
}
