Commit new solution files for Data Structures

[Kvaibhav01]

Visit HackerRank's Data Structures website, visit the subdomains and commit new problem solutions at the repo's Data Structures folder.

Rules:

1. Solutions must be correct (obviously), I will review them before merging.
2. The solution's directory path must be according to the subdomain HackerRank provides for Data Structures. Example: /Data Structures/Subdomain name/Solution.java or /Data Structures/Subdomain name/RelevantFileName.java
3. Code can be done in any preferred language but Java and JavaScript are recommended. Someone who provides the solution in Kotlin/PHP (or any other language except recommended ones) will be considered later.
4. Code should be formatted properly. Unformatted code will be disregarded.
5. The solution you submit should be of your own.

Hey, can i work on this ?

[Kvaibhav01]

@rajvijen yes, it will be accepted but if someone provides a correct solution for the same with Java/JavaScript then his/her solution will be added.

@cfsnsalazar @aayushbhan you can start working but make sure you follow the rules and you don't work on a same problem.
