Understand logic of Merge list non recursively in details

[prasadtelkikar]

• Solved MergeList-NonRecursively by looking into StackOverflow solution. This is not going to help me in long run.

• Dig more on the internet, find better resources for Merge List non recursively from the internet. Understand it in details

• Same for Reverse linked list Recursive and non-recursive problems.

• Problems to understand in detailed:

1. Merge Two ordered lists Recursively.
2. Merge Two ordered lists Non recursively.
3. Reverse linked list Recursively.
4. Reverse linked list Non-recursively.

Help needed to get correct resource to understand above problems in details.
