LeetCode 707 C Solution – Design Your Own Linked List [add/get/delete] | Linked Lists in C

LeetCode 707 C Solution – Design Your Own Linked List [add/get/delete] | Linked Lists in C

In this tutorial by CodeWithBK, we’ll implement LeetCode 707: Design Linked List in pure C, without using any built-in list libraries. You’ll learn how to:

✅ Define a ListNode struct
✅ Initialize your custom linked list
✅ Implement key operations: get(index), addAtHead(val), addAtTail(val), addAtIndex(index, val), deleteAtIndex(index)
✅ Handle edge cases like invalid indices and empty lists
✅ Optimize for time and space complexity

This video is perfect for:
- C programmers preparing for coding interviews
- LeetCode enthusiasts improving low-level data structure skills
- Anyone learning dynamic memory management in C
