Hello,

I try to add recursion function to find the min in this program it gives me error i dont know why if you can help me please? i know the Find_min funcrion it is

int Find_min(Node *head)

{ if (head == Null) return INT_Max;

else{ return min(head->data, Find_min(head->next));}}

but when i add in my LintegerLinkedList it giving me error the complete code is :

/IntegerLinkedList.h

#pragma once

#include

#include

using namespace std;

struct node

{

int value;

node *next;

};

class IntegerLinkedList

{

node *head;

public:

IntegerLinkedList();

void addFront(int val);

void deleteSmallest();

string print();

};

------------------------------------------------

//IntegerLinkedList.cpp

#include"IntegerLinkedList.h"

IntegerLinkedList::IntegerLinkedList()

{

head = NULL;

}

void IntegerLinkedList::addFront(int val)

{

node *newNode,*next;

if (head == NULL)

{

head = new node;

head->value = val;

head->next = NULL;

}

else

{

newNode = new node;

newNode->value = val;

newNode->next = NULL;

//save next pointer

next = head;

head = newNode;

head->next = next;

}

}

void IntegerLinkedList::deleteSmallest()

{

node *cur = head, *prev = cur,*next=NULL;

int min = cur->value;

//first find smallest number in list and then delete

while (cur != NULL)

{

if (min > cur->value)

{

min = cur->value;

}

cur = cur->next;

}

//now delete the min by searching the number

//if smallest is at head

if (head !=NULL && head->value == min)

{

prev = head;

head = head->next;

delete prev;

}

else

{

cur = head;

/*if (cur != NULL)

{

while (cur->next != NULL && cur->next->value != min)

{

cur = cur->next;

prev = cur;

}

cur->next = NULL;

delete prev->next;

}*/

while (cur != NULL && cur->value != min)

{

prev = cur;

cur = cur->next;

next = cur->next;

}

prev->next = next;

delete cur;

}

}

string IntegerLinkedList::print()

{

node *cur = head;

string str;

while (cur != NULL)

{

str += to_string(cur->value);

str += ' ';

cur = cur->next;

}

cout << str<

return str;

Thank you for your help.
