Here is my C++ solution, you can watch the explanation here : https://youtu.be/jCPAp_UIzAs

SinglyLinkedListNode* insertNodeAtPosition(SinglyLinkedListNode* llist, int data, int position) {
    SinglyLinkedListNode* newNode = new SinglyLinkedListNode(data);
    if(position == 0) {
        newNode->next = llist;
        return newNode;
    }
    SinglyLinkedListNode* curr = llist;
    while(position - 1) {
        position--;
        curr = curr -> next;
    }
    newNode -> next = curr->next;
    curr->next = newNode;
    return llist;
}

The provided classes for C# do not compile. This needs to be fixed.

Apparently I can't debbug my code because there is offuscated code that has an error that I CAN'T EDIT, for Java 8 it dosen´t work.

Solution: I suggest you to delete the class Result{} <-- including the brackets and leave only the method declared as public static

SinglyLinkedListNode* insertNodeAtPosition(SinglyLinkedListNode* llist, int data, int position) { SinglyLinkedListNode* newNode = new SinglyLinkedListNode(data); if(position == 0) { newNode->next = llist; return newNode; } SinglyLinkedListNode* curr = llist; while(position - 1) { position--; curr = curr -> next; } newNode -> next = curr->next; curr->next = newNode; return llist; }

Is it only me or others also getting error on the code without writting a single line of code. I am getting the error as given below:

Solution.java:78: error: Illegal static declaration in inner class Solution.Result public static SinglyLinkedListNode insertNodeAtPosition(SinglyLinkedListNode llist, int data, int position) { ^ modifier 'static' is only allowed in constant variable declarations Solution.java:109: error: cannot find symbol SinglyLinkedListNode llist_head = insertNodeAtPosition(llist.head, data, position); NOte: I am using java version 7 to run the code which was default ^ symbol: method insertNodeAtPosition(SinglyLinkedListNode,int,int) location: class Solution 2 errors
