How do I code this problem

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

//Creating the struct
struct Student {
	char name[50];
	char gender;
	struct Student* next;
};

struct Student* insertNode(char* name,
	char gender, struct Student* list)
{
	struct Student *s;
	//Allocate memory for node (malloc operation)
	s = (struct Student* )malloc(sizeof(struct Student));
	if (s == NULL)  {
		printf("Memory allocation failed.");
		return list;
	}
	strcpy(s->name, name);
	s->gender = gender;
	s->next = list; //list is the start of the list
	list = s;

	return list;
}
//Sorting function
struct Student* sortList(struct Student* list)
{
	//Write your code here
}

//Printing function
void printList(struct Student * list)
{
	while (list != NULL) {
		printf("%s\t%c\n", list->name, list->gender);
		list = list->next;
	}
}

int main()
{
	//Creating an Initial Node Variable
	struct Student* head = NULL;
	//Call to functions
	head = insertNode("Cenk", 'M', head);
	head = insertNode("Ceyda", 'F', head);
	head = insertNode("Esra", 'F', head);
	head = insertNode("Okan", 'M', head);
	head = insertNode("Tugce", 'F', head);
	head = insertNode("Mehmet", 'M', head);
	head = insertNode("Ayse", 'F', head);
	head = insertNode("Merve", 'F', head);
	head = insertNode("Sedat", 'M', head);
	head = insertNode("Ahmet", 'M', head);
	//call to sorting function
	head = sortList(head);

	printList(head);

    return 0;
}
