Refactor the project

[Pradyuman7]

Similar type code directories should be placed inside a parent directory. Example:
Many code directories are just algorithms, they can be placed inside a parent directory with name algorithms.

Existing code in repo contains errors. Two classes have mismatch between class name and .java file name

class TopKFrequentElements in TopKFrequent.java

and

class SinglyLinkedList in LinkedListOperations.java.

I'll fix classes that causes errors and commit - I'll use class names as template for file names as I assume they have priority.

Clean up the code and refactor it to remove all the irregularities introduced by new PRs

[Pradyuman7]

For this issue, please make sure you do the following stuff:

1. Merge directories that have similar code content and remove duplicate codes in the merged directories
2. Make each directory a maven module properly
3. Simple clean up that you find fit
