New Interesting problems can be added into misc folder

[Vishruth-S]

The "misc" folder looks kinda empty . It would be nice if we can have more potential Interesting problems from CP :smiley:

Any problem that you add must satisfy the following

• The problem must be related to the Competitive programming domain
• The problem must be your own. You may add your name as Author and add any personal links if you wish to.
• You can name the problem anything you like. Also give the same name to the folder.
• The problem.md file must have the following
  • Problem statement which is clear and easy to understand
  • Input format, Output format
  • Constraints (if any)
  • Sample testcases with detailed explanation to at least 1 or 2 depending on the difficulty level
• You may also add additional testcases in a separate file called testcases.txt
• Adding a solution is optional. Please refer Contributing.md if you are planning to add a solution as well

If you have got some of your own interesting questions which satisfy all the above, then feel free to send a PR and reference this issue :grinning: :sparkles:

(Note: The idea is to collect some potentially challenging questions. Hence please avoid trivial questions like swap 2 numbers, finding factorial/fibonacci, largest of 3 numbers etc :sweat_smile:).
