LeetCode 21: Merge Two Sorted Lists — Step-by-Step Visual Trace

1. 1Read the problem statement on LeetCode 21 and understand the requirements
2. 2Create a new dummy node to serve as the start of the result list
3. 3Compare the values of the nodes in the two input lists and append the smaller value to the result list
4. 4Repeat the comparison and appending process until one of the lists is exhausted
5. 5Append the remaining nodes from the non-exhausted list to the result list
6. 6Return the next node of the dummy node as the result

Software engineers and developers can benefit from this tutorial to improve their problem-solving skills and data structure knowledge, especially when working with linked lists.

💡 Merging two sorted linked lists can be achieved by comparing node values and appending the smaller value to the result list
