This is my solution: https://ideone.com/cz06mj

I seem to pass all test cases except one, the last one!

Sorry if I seem to be asking every question on the forum, but getting to know the fault in the codes will help me be an ace in ZCO. I appreciate all the help provided by the forum.

Thanks for all the help!

Regards,

Arnav
