[Sid672]

@aschkun this issue is open for all because everyone likes problem-solving if I assign issue to you then other people will not work on it so I am not assigning this issue to anyone. You can continue your work buddy.

Hey!
came across this issue, so basically I have to add the problems solutions from different platforms in their respective folders? irrespective of their sub topic like Arrays, Strings or so right?

[Sid672]

Right, @parth-gpt. But all solutions must be written in Java.
